Weight reduction and rotating mass – reduce your cars weight for more fun!

You want to have fun in your car, and have some enjoyment in the twisties and corners.

People are very often concerned about making more horsepower, having a better sound system, etc and one area thats frequently overlooked is the weight of the car, and more specifically rotating mass weight.

Now, any car can benefit from a weight reduction, but how extreme you want to take it depends on you.

Take for example our 2014 Dodge Dart GT.

One of the things we did to change our cars look, was to get a set of 18 inch Enkei PF01 wheels. These replaced the factory Dart GT wheels that looked like this.

Now, we dont have exact weights available at time of making this article, but the factory GT wheels were very heavy, and weighed something like 24/25 lbs each. The Enkei wheels we put on that you can see below weighed in at 18/19 lbs. Thats a savings of about 6 lbs on each corner.  That may not sound like much, but a 24lb weight savings on wheels is massive.

Now, with these new wheels, we noticed a difference in acceleration off the bat, the car handled better, it revved up much faster, and felt faster overall. This is because, in general anything that is rotating mass – ie, wheels, tires, brakes, axles, rotors, engine internals directly affects the engines performance.

Now, we also did some other work to our Dart to reduce weight.

Brakes – we used a custom made brake kit to reduce 16 lbs of rotating mass.

Pulley -we installed a lightweight crank pulley to reduce 3 lbs of rotating mass.

Seats – we pulled out the leather seats and installed cloth seats to save nearly 30lbs of weight. Most of the weight savings were from going from full power seats to manual seats, no heavy motors attached to the cloth seats!

So, we have reduced nearly 50lbs of rotating mass, and about 30 lbs of fixed mass. This is pretty incredible and its a difference you can feel when driving our Dart.

Morale of this story is – when you are modifying your car, keep the weight in mind!

Or, to quote the founder of Lotus automobiles, the lightweight, fun roadsters –

“Simplify, then add lightness”!



Diablosport Trinity vs Intune2, whats the difference?

Diablosport Trinity vs Intune 2 – whats the difference?
Check out our handy graph below.


As you can see in the graph, they offer the same features, EXCEPT, the Intune you flash your car with, and put the Intune in your glove box, or in storage.
The Trinity on the other hand, is designed to be mounted in view for you to watch engine parameters. You can select whatever you want to monitor on the customizable graphs on the Trinity.
Watch to watch timing, knock, fuel pressure, boost pressure, etc, you can select it, and monitor it in real time with the Trinity.

The Trinity also offers drag race mode which allows you to time your car to see how fast your car is in the 1/4 mile and 0-60, etc.

Other than that, both offer the exact same performance and tuning capabilities.

New wheels for the Caliber SRT4 project car ..

We were getting a little tired of the the factory Caliber SRT4 wheels, and decided to get some new wheels for it. We wanted to get a black spoke wheel with a polished lip.

In this blog post: we tried fitting a different set of wheels on the Caliber SRT4 but they didnt fit due to clearance issues with the Caliper.


Heres the specs of the wheels.

Petrol Vengeance

19×8 inch

40 offset

5×114.3 fitment

We’ve got tons of clearance between the wheels and the caliper, and if we had to order wheels again we would more than likely get a wheel with less offset for more of a lip.

MPx Blow off plate for Neon SRT4 and Caliber SRT4 now available! $34.99!

Mpx Blow off plate for Neon/Caliber SRT4

Introducing the MPx blow off plate for the 08+ Dodge Caliber SRT4, 03-05 Dodge Neon SRT4 and the 02+ Plymouth GT Cruiser.

This piece mounts under the factory turbo relief valve and allows the pressurized air to be released when ever you push in the clutch or release the gas.

Want to install a blow off valve onto your Neon SRT4 ,Caliber SRT4? Then you’ll need an uppipe!

Want to install a blow off valve onto your Neon SRT4 ,Caliber SRT4? Then you’ll need an uppipe!

If you have decided to install a new blow off valve on your Neon SRT4 or Caliber SRT4 so that you can turn up the boost without the factory blow off valve leaking, or if you just want a cool sounding blow off valve, youll need to mount a uppipe with flange onto your car.

Why you might ask ? Well the answers simple! The factory blow off valve has a flange that does not work with any aftermarket blow off valves from Hks, Greddy or TurboXs. So, you have to have a pressure pipe with a flange to mount the blow off valve onto. Thats where the uppipes shown below come into action.

The first one is a AGP uppipe for the 03-05 Neon SRT4. The second one shown is the MPx uppipe for the Caliber SRT4.

MPx uppipe for Caliber SRT4

Both of the pieces above will replace one of the pressurized sections of piping on your car, and allow you to mount a new blow off valve.

Photos of our color matched MPx Dual/Triple Caliber SRT4 pillar pods being painted

Today we painted a small batch of Caliber SRT4 Dual/Triple pillar pods and I thought it would be good to show/discuss whats involved in us making these.

First off, Modern Performance worked with a manufacturer to produce these for the Caliber SRT4, and the finished product looks great, however theres one major issue. The manufacturer couldnt produce the pillars in the same color as the factory A pillar. So the a pillar pods are delivered to us in black.

We then had Sherwin Williams paint match the factory A pillar with a special automotive grade paint that flexes with heat and cold. This paint is expensive, and it requires a multi step process to make sure the paint adheres to the pillar perfectly.

The first step is to clean the pillars with a special cleaning agent. Then, we spray a primer on the pillar to prep the surface. Lastly in the painting process we spray the pillar with the custom matched paint.

Then all of the pillar pods are moved outside to bake in the sun for a few hours, followed by curing indoors overnight.

At this point, we compare the painted pods to the factory pillar to make sure the color matches perfectly.

To make sure the pillar pods arent damaged in transit, we then take each pillar and wrap them in bubble wrap. Its quite a process, and it involves a lot of work, but we do it all the right way to make sure they look good, and will last in your Caliber SRT4.

Caliber SRT4 Valve covers – slowly but surely getting the color matched for powdercoating

I know its been a while since we last gave you an update on the powdercoated valve cover for the 08-09 Caliber SRT4.

The delay we have had, is because our powdercoater has had a tough time making an exact match of the Inferno Red color.

Heres what the powdercoater has come up with..

Here we have a budweiser (or is it bud lite) can that has been powdercoated with a sample color match next to our project 2008 Dodge Caliber SRT4.

Its very very close, but we are going to make another change to try and match it a little better.

Washed, Cleaned, and Paint Sealanted the 08 Caliber SRT4 this weekend

Most of you out there are familiar with waxing your cars, and how your car needs to be waxed every 2-4 months. The process of waxing your car can be very time consuming, and most of us drivers want to take care of our cars but dont have the time to wash, claybar, wax, and then buff our cars. That process for one person can take up to 5-6 hours !

So, another option to keep your car shiny, and protected from bugs, bird droppings is paint sealant. Paint sealant usually lasts about a year, and is very durable, easy to work with.

So, this weekend, I took our project Caliber SRT-4, washed it, used paint cleaner from Meguiars, and then used Paint Sealant from Griots Garage. The whole process took about 2-3 hours, and now the cars protected! Most people will never even know it has paint sealant versus wax protection too!

Onto the photos!

It looks GREAT now ! Look how glossy it looks and the reflection on the side of the car!

2008-2009 Dodge Caliber SRT4 owners who change their own oil, take notice!

Just a note for those of you Caliber SRT-4 owners who change your own oil..

About every 4,000-5,000 miles your Caliber SRT-4 will make a BING noise and your display will read CHANGE OIL SOON.

Now, for those of you who go to dealerships to change your oil, no problem, they will reset the message for you. BUT for those of you

who change your own oil, you may be wondering how to erase/reset this message.

Its actually quite easy to do and theres no special tools involved !

Put your key in the ignition, turn it to the ON position but dont start the car. Then, push the accelerator pedal to the floor and release 5 times.

Then, start your car, and the message will be reset ! PRESTO !

Pictures from 7-18-09 SRT-4/Neon/Caliber meet at MP.

Modern Performance 7-18-09 Meet

Modern Performance held a Neon, Neon SRT4, Chevrolet Cobalt, and Caliber SRT4 meet on 7-18-09 and we had in excess of 60 cars show up.

The meet took place in Houston, Texas at Modern Performance’s office/warehouse.

MP hosted the meet in the heigth of July, which is one of the hottest months of the year, and it was a challenge to keep everyone cool when it was 90-100 degrees outside!

Throughout the day, we had the following show up at the meet :
7-8 1995-1999 Dodge Neons
2-3 2000-2005 Dodge Neons
40-45 2003-2005 Dodge SRT-4’s
4-5 2008-2009 Dodge Caliber SRT-4’s
2-3 2005-2009 Chevrolet Cobalts

We didnt take count of how many people showed up, but it would not be suprising if we had in excess of 75-100 people.

Throughout the day, MP provided :
320 Cokes, Sprites, Bottled waters
75 cookies
15 Large Pepperoni, Hamburger, and Cheese pizzas

At the end of the day, there were NO food, or drinks leftover!

Anyways, onto the photos!

Mopar Manual trans fluid in stock for 95-05 Neon, 03-05 SRT-4, 08+ Caliber SRT-4

Mopar ATF+4 Fluid

We get a lot of calls from customers asking what type of oil they should be using for their vehicles, due to confusion at local dealerships. So, to make it easier, we have stocked up on plenty of Mopar Official manual transmission fluid and we can ship it right to your doorstep to make it easier.

So now, when youve got a good amount of mileage on your car, or are doing a clutch job and want to refresh the manual trans fluid in your car you can get the correct fluid from Modern Performance!

Now, we are listing this fluid as Manual transmission fluid, however the label shows ATF+4 in the picture and you might be a little puzzled. Mopar used ATF+4 in all of the manual transmission Neons, Neon SRT-4’s as well as Caliber SRT-4’s and so as weird as it might seem, this is the right stuff!

2008-2009 Caliber SRT-4 – Fill Capacity 4 Quarts of ATF+4

Please note: This is the fluid recommended by Mopar for the vehicles above. If you drive your car very hard, a Chrysler Engineer that we work with quite a bit has recommended the use of Mobil 1 High Mileage 10w/30 with ZDDP or Zinc dithiophosphate which helps protect the gear surfaces better under high heat conditions. You can find the ZDDP labeling on the back of the container.

Want to find out more about ZDDP ? Check out more details on Wikipedia.org with this link..
