Offset Question

[R TUNE]

ok guys can some one help me with this.

i req new rims as the rims i have, the offset is now to big for the for the front brakes and i have to run a 20mm spacer (+40mm offset rim)

would a +34mm with a 5mm spacer work. the reason why i wont to go to a 5mm spacer as i know it does not throw out the balance like the 20mm and it will also bring the track width in.

if i am corect the perfict offset would be 25mm front and 30mm rear for my car.

i have r33 gtst front brakes (HR31 struts) and std rear brakes.

+40 rim with a 20mm spacer = effective offset of +20

+34 rim with a 5mm spacer = effective offset of +29

So the +34mm rim combination has 18mm less track than the +40mm rim combo. Offsets and rim size can be used to determine clearance to the strut and guard, but they can not be used to determine clearance to the caliper, spoke design comes into it for this. The only real way to find out for sure is to bolt it onto the car and see if it clears the caliper.

Also a 5mm slip on spacer is much more likely to throw out the balance than a 20mm bolt on or a 20mm hub centric slip on (like H&R)

thanks for that.

i have found that the 5mm spacer didn't throw out the balance, but the 20mm did

if possible dont use spacers at all, just get the right offset rims to begin with that have aspoke design that wont foul the brakes.
