GT4 track alignment - parts heads up
#31
Burning Brakes
I had my car (mileage = 3,577 km) aligned today in preparation for the last track day of the season on Monday. The stock alignment was approx. neg. 1.4-1.5 on all wheel, but the toe was way out. I had toe in on diagonal wheels and toe out on the others.
In any case, they set front camber to -2.0 with approx. zero toe. They managed to get 1.6-1.7 degrees neg. camber on the rear (with 0.10 degrees toe on each wheel). The note on the work order stated:
Just another data point.

Rear camber is maxed out, rear toe can only be further adjusted with aftermarket links.

installed shims today to have more camber ... my stock settings were -1'5 front and 0 toe and -1,25 rear with 0.10 toe in.... with 7 mm shims in the rear (+5 mm compared to stock) and + 5 mm in front (7mm shim stock plus a 5 mm shim)... we were not able to align the car in the rear with more camber without run completely out of spec with the toe.... i need new links... with only the shims i did not resolve anything..... aaargghhhhh
The rear left was ok. . .. but with the rear right one was impossible to achieve our goal.. max camber was - 1,25 with the correct toe measure ... 0.10... with more camber the toe was totally out of spec...

I purchased the TPC rear toe links anticipating this problem......I left rear camber at -2 deg. Still playing up front with -2.5 right now. Don't want a too aggressive setup as I use the car a lot on the street.

The track of the GT4 is wider than the normal cayman, but they kept the original cayman toe arms - the adjustment is already pretty max'd out.

The only suspension mods I have are RSS rear links and -3.0F -2.75R. The car seems to handle well on track and is still good on the road though it's not a DD. I did a 700kms mix of freeways and back roads (plus a track day in between) last week and it was an easy drive without it wandering around the road. I also have a DSC unit but, to be frank, it doesn't seem to do much.
