Grassroots Motorsports $2004 Challenge - RX
Posted 04 April 2004 - 08:58 PM
1987 RX - 3 Door
Drag Strip: Best time 16.3sec 1/4 mile
Autcross: Best time 57.7xx (ftd was 54.6xx I belive and it was a GLHS Omni IIRC)
Car show we finished just above the top 1/2 of the cars.
The mods of the car: cone filter, no 2nd cat, glasspack muffler, stock downpipe. Delta Cams, fresh head job, 14psi stock turbo, springs 250lb front 300lb rear, custom made camber/castor plate. Engine reassembly using stock gasket kit, new water pump, several new hoses, new stock clutch.
The car roasts the tires on launch at the strip, and revs very freely into the redline with no fuel cut. I did notice fuel cut a couple of times when entering the interstate. It wasn't at full throttle, but rather 75% and only when sitting around 10psi.

How much did you spend on the camber/caster plates? How did you figure where to place the bearing? Did you make them or have them made? I want some!
They were custom made by one of our local autocrossers. He said he would make more, but wanted $200/set as he wasn't really interested in making more. It's very possibly you can use a Impreza/Legacy/WRX front camber plate. I know wjm had to slightly modify the old set I had on my legacy, but he was able to fit them in both his rx and his wagon. The one downside was having to pound in the bump on the inside of the strut tower for spring clearence. I may consider making some of those plates cheaper if the person who designed it doesn't mind, and I find a good source for the bearings.
