Toyota Supra MkIV Twin Turbo

1995 Black GZ Aerotop (Automatic).

This is my latest purchase, a 1995 Toyota Supra MkIV Twin Turbo GZ Aerotop automatic.

Here are some more pictures.

My OLD SUPRA. Click on it to see what she was like, and what she's like now!.....

Previous stock wheels were Toyota rims with
Rear 245*45 ZR16
Front 225*45 ZR16 Tyres
I now have 18" Speedline Aliseo 3 piece split rims with
Rear 265*30 ZR18
Front 245*35 ZR18

What is the stock alignment?
Front : Camber -0.5 degrees +/- 0.75, Caster +3.5 +/- 0.75 degrees, Toe 0.00 +/- 0.80" (2 mm)
Rear : Camber -1.50 +/- 0.75, Toe 0.120" (3mm) Toe IN +/- 0.080" (2mm)

What is a good street alignment?
Front: Camber -1.0 , Caster +5.0 , Toe 0.00
Rear Camber -1.5, Toe IN 1.0mm
The Front and Rear toe are critical to tire wear, even small deviations from spec may cause unusual wear patterns or excessive wear.
