noob rim question...
would a 18x8 rim with a 42+ offset cause any rubbing
on a fto with stock suspension?
if not what tyre size should I go for?
or what offsets suit a fto with 18's?
cheers and sorry if its been asked before!!!

18x8 wouldnt fit on a fto youd get a whole lot of running on the inside
on my last wheels i had 18x8 with a 35 offset and i had to roll the lips and they did fine only rubbing a bit on full lock. if im correct, with the lower offset it will push the centre of the rim outward to minimise rubbing (if any rubbing at all).
why what rims you thinking of running?

A +42 offset is too much - it means the wheel will rub either on the wheel arch liner, the suspension or the inner arm.
Here's my annual 'offset explained'

The offset is where the mounting point on the hub is positioned in relation to the centre line of the wheel.
A positive offset will mean the mounting point is closer to the outside of the wheel, which means it will sit further in.
A negative offset will mean the mounting point is closer to the inside of the wheel, which means it will sit further out.
If it's too far in, there is the potential for it to rub either on the wheel arch liner, the suspension or the inner arm. Thats why spacers are often used.
If it's too far out, there is the potential for it to rub on the inside lip of the wheel arch, which is when rolling the arch can be done.

more than likely unless you going to buy springs and get them to fit while your therexSlurpee wrote:ahhh explained, my CRISS's ex gramlights rims rub on my suspension ...
bushido, say i visit wholesale suspension and have the intentions of buying some springs. Would they charge me for the labour of trying on the rim on a hoise and finding a suspension to rectify the rub?

Bennoz- I think its on a small part of that plastic stuff that makes up the in side of the wheel arch...splash shields?
vipfto- yes, and not sure... i don't think so for some reason, not unless they have worked themselves loose since i bought the car (not that long ago)
FTO-LEO- damn, its sucks ay... kinda sounds dodgy when your pulling out of tight spaces
Ed_EViL- couldn't say...can't remember off the top of my head what the size of them is. Whats the right size anyway?
The car is low, not rediculus... but pretty low

Would it be cheaper to get a new set of semi slicks or just some 25mm spacers and the costs involved with new studs, wheel alignment etc to get rid of my rubbing?

This true, but you can combat that to a point by ensuring the spacer is of good quality & has the centrebore shoulder machined into it (that small ridge that locates the wheel in the centre)col2560 wrote:am i right in thinking that the load centre of the rim should be centered over the bearings so they dont wear out ??
changing the offset too much will chew bearings???

You'd also need longer wheel studs - sometimes they come with the spacers
