A9H-RX Posted April 16, 2013 Share Posted April 16, 2013 Found a set of Rota GTR wheels I want I had a previous set 18" with 8.5J with 35 offset on front and 9.5J 30 off set on rear, fitted nice with no problems before an Audi driver ripped them to bits. I have found a new set which are exactly same but front ET is 20 and rear ET is 35. Is this going to be a problem with clearence? Spacers needed? Car will be lowered by 30mm if that makes any difference?! Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted April 16, 2013 Share Posted April 16, 2013 On the new set, the fronts will sit further out, so no issues with clearance but the rears will sit further in, there shouldn't be a clearance issue with the offset but they will sit further in than your last set...

Is offset figure a mm measurement? and also lower the offset, further out they sit and higher the offset, futher in they sit? (assuming sitting in the wheel arch and not actual dish of the rim)?

MITZ@CougarStore Posted April 16, 2013 Share Posted April 16, 2013 Offsets are measured in mm, and you're right, the lower the offset the further out the wheels sit, so offset of about 40 will be lost in the arch and an offset of 20 will most likely sit in line with the arch...

Sweet! Now that's easy to understand! haha You wouldn't know best offset for 350z to get rims sitting flush on wheel arch? Quote Link to comment Share on other sites More sharing options...

When we supply wheels, we tend to opt for an offset of 20 or as close as, have a look at our thread here, these all have an offset of 20 in the Rota GTR wheels we've supplied - http://www.350z-uk.com/topic/32711-rota-gtr-wheels-%e2%80%93-350z-fitment-from-cougar-store/ Quote Link to comment Share on other sites More sharing options...

Just for future reference, what's the price range of your rims with and without tyres? Quote Link to comment Share on other sites More sharing options...
MidnightRacer Posted April 16, 2013 Share Posted April 16, 2013 Don't forget offset is also relative to the width of a wheel. a 20 offset will have a different outcome to arch gap on an 8 inch wheel to that of a 9 inch wheel. (as its measured from the centre of the wheel) Quote Link to comment Share on other sites More sharing options...
MITZ@CougarStore Posted April 16, 2013 Share Posted April 16, 2013 For reference, 19" wheels in GTR are circa £960 and tyre prices tend to change daily, so drop us a call or email and we'll be happy to assist... Quote Link to comment Share on other sites More sharing options...
