Grassroots Motorsports: The Hardcore Sports Car Magazine

We’ve wrapped up the editorial on the Project SRT-4. It has left our stables and is now living with a reader in Wisconsin.

You can buy back issues covering this project by calling us a (800) 520-8292.

Here’s the dyno chart from Projekt7.

The TCE kit is simple and straightforward to install. We had to use the spacers (in foreground) that measure 1/4" for even our new wheels to fit.

Installed, the TCE brakes work very well with awesome pedal modulation and no fade.

The SRT4 now turns some simply amazing lap times, thanks to its competent suspension, great brakes and gobs of horsepower.

The Forge Motorsports blow-off valve and wastegate actuator netted us 12 horsepower and 70 lb.-ft. of torque. The surging issue with the stock blow-off valve is gone and the car a rocketship.

We also installed our big brake kit from TCE and new Konig wheels. The car goes, stops and handles very well on track, turning some of the fastest lap times we’ve ever seen on our test track.

These installs will be written up in the April and May issues of Grassroots Motorsports, as the sixth and seventh portions of this project.

The Hurry weighs in at 18 pounds in a 17x7 size. They’ve got quite a bit of caliper clearance for big brake kits and they’re inexpensive.

We’ve just received some new wheels for our SRT-4. The big brake kit that we’re installing requires a wheel with a fair amount of caliper clearance. We got Konig’s new Hurry wheel in both black and silver. The black set will be our street wheels, while the silver will be perfect for our race-only Hoosiers. We’ve got Hankook K104 tires on the way for street use.

Now we can install those TCE big brakes!

We also did some baseline brake testing. On stock pads, the car stops from 60-0 in 130 feet. With Hawk HPS pads, the distance dropped to 121 feet. There was noticeably more brake torque with the new pads, as you had to threshold brake from 60, instead of around 45 mph.

We’ve also got a blow off valve and an adjustable wastegate actuator from Forge Motorsport that we’ll be installing while the folks from Sports Car Revolution film us.
