ok...i will bite.
why/how would you purpose lengthening a 1st gen's wheelbase?
trackwidth 2-3" could be done with back spacing and some SUBTLE fender flaring, im not talking box flares or 70's bolt on flairs....but tastfully done it "could" almost blend in, unless you enhance it with brake vents(BM cars
)
the main problems i see would concern the front if you subtract backspace.... the scrub radius would be the most noteable change, increased wheelbearning stress...etc.
the "wider" makes sence (more stability), but i dont "get" the longer. too many downfalls to go with the only real "pro" of a better ride, and more straight line high speed stability.
