new wheels!! (spring question)

[alan pritchard]

finally got my new (to me) alloys on my cgt, theyre like golf gti cross
spoke jobbies (bbs style?). 7*15" i wanted large tyres (225/45 15) but
couldnt get any cheap enough, got a set of part worn 205/50 15 for 100 quid,
fitted and balanced. good job, these wheels had a larger offset and just
fit, i think the rear  left maybe just scrubbing. the car looks great,
unfortunately  the front looks slightly high but the rear is perfect.  i
need to get a pair of coils (uprated with 30-40mm drop) for the front. has
anybody got any idea of the specification (ie size, rating) or would i just
have to buy a set of 4??

ps is cutting a good idea? (on a budget)
