I ended up autocrossing my Subaru instead of the Fiero on Nov 3rd, so this coming weekend will be my 2nd event.
I still haven't revalved the shocks, nor replaced the front left. The reason being I haven't had a chance to take the car somewhere with scales, since I had to replace my clutch and flyhweel. The shocks will just have to do for now.
Notable changes since the last event:
New wheels and tires
(see
The SERIOUS Wheel & Tire Thread for more details)
Motegi MR116 17x7-48mm and 18x9-45mm with 215/45/17 and 275/35/18 Hankook RS3:
The fronts weigh 42.6 lbs with tires. The rears I Iost my notes on, but they should be ~50 lbs.
They're light, but they were cheap, and had the right sizes and offsets.
Fieroguru's lateral link relocation brackets
These brackets lower the lateral links by 38mm at the knuckle/upright end. You can buy them directly from Fieroguru.
The brackets should improve the camber gain and increase the roll center. Both of these factors will help improve rear grip.
New alignment
I redid my alignment. New settings:
Front camber: -1.0 deg
Rear left camber: -1.8 deg
Rear right camber: -2.3 deg
Front toe: 0"
Rear toe: 0"
I might change the toe before the autocross. I previously ran 1/4" toe-in up front and 1/16" in the rear. I want to see how it handles on the road with neutral toe first.
New front springs
West Coast Fiero 400 lb/in springs with ~3/4 coil removed (if I remember correctly).
Ride heights are now 350 mm up front, and 370 mm in the rear.
I can't find my notes on my previous front ride height. I didn't adjust the rear since last time, but the front got new springs. All ride heights are measured from the top of the wheel arch to the center of the hub, with 3/4 tank of gas and 140 lbs of ballast in the driver's seat.
Note that the new front tires are shorter and the new rear tires are taller, so the actual attitude of the car has changed (more forward rake) despite the arch-to-hub distance being pretty much the same.
Revised link lengths
I reverted my adjustable lateral links to stock lengths (based on Bloozberry's measurements), and adjusted the toe link for neutral toe. Despite this, I have about as much camber in the rear as before (same on RL, 0.3 less on RR). I probably picked up some static camber from fieroguru's link relocation brackets.
New exhaust
My new exhaust system has a Magnaflow 12265 with resonated tips. It's still a 2.5" system. My previous muffler was a custom thing I made myself that probably didn't flow all that well. It had baffles and stuff in it.
New clutch/flywheel
Clutchnet organic/clutchtex disc with stock steel flywheel. The aluminum one came loose for the 3rd time so I gave up on it; it's poorly designed and the aluminum cold flows under the bolt heads when properly torqued.
I think that's it. I will add more if I remember something else.
