Heres the front set up on the Jzx90,
Billspear Knuckles, 25mm YAJ RCA, Subaru Legacy Rack ends, JZA80 twin Pot Brakes, Genuine Toyota JZX110/SXE10 Castor arms.
Running factory Castor (around 6 degrees) and -4 degrees camber
The Jzx110 castor arms have bigger mounting bolts than the stock 90 ones (m16 instead of m14) so the jzx90 lower arms have to be drilled out to 17mm.
Running 18×9.5 +23 (+38 with 15mm bolt on) wheel ends up with very minimal clearance to castor arm at full lock (see pic).
This kinda explains why all the comp jzx90/100 in japan run the large bolt on’s, just not possible to get near Silvia lock with the stock fenders.
Also last weekend i shorted the factory rear Toe and Camber arms by 10mm, i figured this would be way better than running some junky china arms and would be alot better for street driving. At the middle of the cam bolt adjustment this shows the camber, before it was the same as the front.
