Apparently, the CSP guys take weight over all else. They remove bracing, don't run shock tower braces or roll bars, convert to the smaller 1.6 brakes, etc.

Probably not healthy for the car's unibody to run that way with a stiff suspension and R tires... but it must be the fast way or they wouldn't do it.

The Honda guys are the same way. Shave as much weight as is allowed and get as much power as is allowed.

Sweet. I didn't know that. MORE years I can include in my search.


I too was unaware of the different gearing, if the 1.8 is actually 125 lbs heavier than a 1.6 equipped car, I'd say that the reduced weight and ability to run the viscous diff make the 1.6 a better starting point.

It doesn't hurt that by being slightly older it should be a little bit cheaper to purchase one as well.

Yeah, the more I think about it, the better a 1.6 sounds.
