Yeah, because a larger rolling radius reduces the factory over-read error.

ahwell all mine are wrong then yet the speedo reads right according to when it was tested :|

all got 185/65r14's......

Paul - factory standard are 185/60/14.

You only get 65 profile on a 14 if its in 165 width, like SRi/1400 Sport.

LMAO


traction has nothing to do with the size of the wheels. most race corsas use 13, 14 or 15" wheels. (as they are lighter and less rolling radious when used with low profiles, thus giving better acceleration) traction depends on what tire grade, how much tread, and width

same engine im 17 stone my m8 is 11 and my other m8 13 he had 2 in his car i had 3 and the big wheels and lowered! but im losing a lot of traction with the wheels i have yea

Could be any number of things mate.

May be the cars will have different amount of milage, meaning one engine may be in better nick than the other. One might have been raced about for a few years by a boy racer, doesnt do the engine any good in the long run. One will have been serviced more times perhaps, meaning it has minimal wear and is running more efficient.
You might have more fuel in your tank, you as a person may be heavier, you may have a lot of ICE, he may not. Other person my have had an induction kit.

I dunno, just puttin a few thoughts up here. These things may not seem that big but a combination of all of the above will defo make a difference between 2 cars with the same engine size

but i have crap wheels there very small 13s or 14s there corsa gsi wheels wat do u think its just traction i think cuz it does spin wen i put foot down, he had 16s and it was low wat do u thimk?

either that or you cant drive :P

j/k

so if i buy the kit that will have wat in it springs and shockers yea? so this bloke must av done something to is engine yea do u think so?

are u trying to say that the springs made it quicker off the mark....

um no they wont.

dont buy just springs doesnt do the handling anygood at all, buy a kit (about £160+) and the handling will improve.

i have 1,6 sport r reg was racing corsa the only difference was that he had 16 inch alloys and lowered springs but off the mark he realy did leave me but after second he was well ahead but in 3rd gear he wasnt pulling away further it was the same he recons i can get springs 4 70 bar wat do u think should i get them, coilovers cost to much but some are saying i might need new shockers wat do u think if i have springs will it handle has good has it does now with standard shit?
