It's not something that's really required. The hottest it ever get's here is 20 degrees C, so as long as the heaters work I'm chuffed . If we do get a sunny day the roof will be coming off (it's a targa top).
Blimey, not updated this in a while. Finally on the road and MOT'd. I've a couple more dyne sessions booked once I change the wastgate springs over, hoping to crack 1000bhp, but that won't be happening until the spring appears and all the salt goes.
Also in dire need of a the suspension setting up, it's like bambi on ice trying to lay any power down at the moment.
Here is the MKIV Supra suspension setup, AKA the Lance setup. Basically it's no toe on front, with all the caster (5 degrees) you can crank in, and minimum toe at the rear.
Camber settings aren't anything wild. 1 degree per wheel up front and 1.5 per wheel in back.
This is designed for good stable handling, and it should result in pretty light steering with all the caster, and even wear on tires. Those may not be your goals, but in lieu of anything else, it's a good start.
Give the image a click & it should open up into a new window where you can actually read it.
