I think just because you said FWD, and we are thinking what you want is a Group 2 car (could be FWD or RWD) and a FWD impreza is still group 2..
If you don't care about which class you end up in . Open Light is pretty happening in most parts of the country. Group 2
is bigger. Probably more tempting to dump money in open light than in Group 2 ..
On paper i like the AE86 Corrolla (83-87 Corolla) 2200 lbs, RWD, and compatible with Some Mr2 engines 53/47 weight distribution.. but they are usually priced way to much because of all the Initial D fan boys etc. (Takumi !!!!)
No clue what their suspension is like. really with any of these cars though i'd just call JVL for suspension ..
240 SX 53/47 weight distribution 2800 lbs
Volvo 240 50/50 weight distribution . 2,800 lb <-- Man if only someone had suggested one of these.. that's some pretty amazing balance!
impreza (90s awd)
58/42 2900 lbs Crappy weight distribution

(fine for racing other imprezas with bad weight distribution though LOL )
Is there a car (not truck) with Worse weight distribution that is used in racing? i can't think of any.
