I have received several requests for information about my set-up so I figured I would
respond to the list. I race in SCCA stock class autocrosses. The rules are VERY
restrictive to try and control costs. I have pretty much done everything that I can to
the car. I have made the following modifications, I have included estimated costs:
1. Koni Sport adjustable shocks. The rear is set almost full stiff and the fronts are
adjusted to the track condition but are normally about 2/3 stiff. The shocks are great,
but the ride may be a little firm for the street. IMHO, use them for racing only. If I
were allowed to change springs I would go to a stiffer spring and softer shocks. about
2. K&N Air Filter... I think it helps. Can't hurt ;-)$40
3. Richened the fuel mixture. Helps HP and hurts MPG. May want to adjust this
inversely with the price at the pump. Free
4. I need to run the stock exhaust through the cats, from the cat back it is free. I
run a two chamber Flowmaster. It is really loud, but I think it sounds sweet.... the
engine screams! This definately increased the HP... may be worth the trade off of noise
to HP for the street. $200
5. New suspension bushings all the way around... big help. I would go to a "stiffer"
material if the rules allowed it. For the street I would go for Delrin or Nylon. I
know Eric was making some trick subframe bushings that may be worth a try.$200-$600
depending on how much you do yourself.
6. Advance the timing. Mine is set to the max of factory spec as the rules allow. For
the street you can crank it up a bit more. Free or $50 to pay someone.
7. Good synthetic oil. It does help the longevity and the performance of the engine.
I use Alisyn Synthetics. $30
8. Remove dead weight. I am allowed to remove the AC and I did so. You may decide
9. Stainless brake lines... a big help. $60
10. Metal Master brake pads.... another help. $60?
11. Alignment.... I have changed mine dramatically to help reduce understeer. It is
great for autocross but would be bad for the road race tracks and the highway... beleive
me I know ;-) $60
I can still make the following mods to my car and I would be curious to hear suggestions
from others as to the advantages gained by:
1. Changing spark plugs... I run cheapo Champions... any suggestions?
2. Changing spark plug wires... I run the 10 year old originals... suggestions?
