Track guys: What would you like to see CSG test?

[Racecomp Engineering]

Brake duct testing is a good simple experiment. We did it a few years ago when we developed our kit for STI. Get some temp strips to make life easy.

I'm surprised no one has asked you to test the Whiteline roll center kit!

This kit?
http://www.whiteline.com.au/product_..._number=KCA313

KCA313 is designed to raise the front roll-centre geometry by using specially engineered ball-joints & tie rod ends while still maintaining original steering geometry. Front roll geometry actually encourages roll the lower you go. Testing proves that raising the front roll-centre resulted in a substantial increase to front roll resistance & a significant reduction in suspension compression of the outside front wheel during cornering (less roll). This improves weight distribution & maintains a better camber angle which ultimately improves front grip. The overall outcome is significantly reduced understeer through reduced front wheel compression as well as improved steering precision & vehicle stability.

Your description states it's essential for lowered cars - if minimally lowered (i.e., with RCE Tarmac 2s), is this still beneficial?

I'd also like to see some data of differnt tire sizes (same compound), which you may already have. I've heard you constantly say that wider tires rob you of straight away speed in a low powered n/a car. I'm surprised that cornering speeds don't make up for these negative effects you've found on the straights.

I might have done that before personally...

That is proof that it's faster at Tsukuba.

That's the one. It will especially help a more drastically lowered car but you should still be able to feel it with a 1 inch drop. I like to think I have a decent butt dyno and I could feel it pretty well on Imprezas with lowering springs. Less noticeable on firmer coilovers.

But...I'd love to see some testing on a BRZ.

I suspect we'll explore RC correction at some point... we're squaring away horsepower at the moment, but looking for avenues to explore next, because we're almost done.

aero tests that apr splitter looks too small to be any use

I will be testing the 4.556 final gear this year and give feedback how much faster, im guessing 3 seconds

Mechanical LSDs?
Different gearing?
Better flywheel/clutch combo? either NA or FI

They generally like to test to socal tracks and I feel ideal gearing is track specific. A shorter gear will give it slightly better acceleration in straights overall but I know many people who prefer the AP1 tranny at buttonwillow vs AP2 despite having "slower" gearing because it saves them a shift to 5th on certain corners.

I have the Whiteline roll centre kit on my car. I'm about 20mm lower on coilovers. Works as advertised - I was getting a whole bunch of bump steer before which is now almost gone, and the steering turns in sharper now too.

Definitely happy with this mod. I'd recommend it to anybody.

A 3rd party test would be great though.

This. I'd love to see the final drive gears tested but I suspect that the benefits might end up being very track specific.

I'd love to see somebody test out various wheel and tire combos on this car, scientifically. It'd be great to know how different rims widths, tire sizes, pressures, compounds and tire models affect performance.

Tires, or aero.
