i know its not a suby but..
i got a 92 Mercury Capri Turbo running 10 p.s.i.
the interior is empty for weight conservation,
2.5" exhaust, cold air intake, and 16" steel wheels with random tires.
Its def not pretty, but really fun to drive.
In the process of building a roll cage.
Its all for fun, not anything serious!
Suspension and handling
Tokico D specs with 04 Sti springs and Whiteline KCA335 front top hats. 2 degrees of negative camber
20mm rsb and kartboy endlinks
04 Sti steering rack
01 GC RS 4.11 LSD rear diff
04 Sti wheels with Star specs for autox and track events
1" addco FSB for track events (I run the stock RS bar the rest of the time)
02 RS wheels with Conti DWS for DD and rallyx (really don't like them, too squishy. Wish i had gotten Dunlop SP60's)
Whiteline subframe lock bolts
Group N engine mounts, tranny mount, and front lower control arm bushings
kart boy front and rear shifter bushings
OBX headers with Sti cat back (yes, it throws a CEL)
Delta 1500 cams
Crawford SRS20 reflash
ACT streetlite flywheel (13.9lbs) and ACT HDSS clutch
K&N panel filter in stock housing
drawtite trailer hitch
outback XT centric premium rotors (thicker than WRX rotors) and WRX brakets for track events. (I use RS brakes for rallyx and DD)
carbotech bobcat pads for the track and generic autozone ceramics for the street
Hawk HP+ rear pads on stock rear brakes
CG lock and Bell Sportmag SA2010 open face helmet
*notes. The nearly 100lb weight reduction in the front raises the car up pretty significantly. I might try JDM Sti pink springs (257lb rate) for the slight 10mm drop.
