I will be autocrossing my 92 Civic Si HB next year, and want to start planning out the setup for it. This is what I already have installed:
Koni Yellow Adjustable shocks
AEM Cold Air intake
DC Sport Ceramic Header
DC Sports front upper strut bar
NoName rear upper strut bar
17" Wheels and tires
Stock exhaust from cat back
Stock Si tranny
Polyurethane bushings all around
This is what I'm thinking of doing:
Replace the 17" W&T's with 15"
Install rear lower tie bar
Install front h-brace
Reinstall stock exhaust manifold.
Polyurethane engine mount stiffeners
It's no secret the 15" wheels are better then 17" for autocrossing. The lower tie bars are to stiffen the chassis. My reasoning for reinstalling the stock exhaust manifold is to gain some low-end torque since the autocross courses are pretty tight, and usually get run in 2nd gear.
What do you guys think? Should I do anything else? This is not my daily driver, but will have to remain street legal. What would you recommend for tires?
