Gretie22 Posted January 17, 2014 Share Posted January 17, 2014 I have had a little search but I'd like a specific answer and I don't want to read every post Right in a few months time I'm going to get some new wheels, I think I'm going to go with XXR 521's. 18 x 8.5 fronts 18 x 9.5 rears or 18 x 10 rears Which offsets would be best. I know the original offset is 50 but I just can't work it out, it's far to complicated for my simple brain. Quote Link to comment Share on other sites More sharing options...

Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 That would be useful if I knew my existing set up Thanks though. Quote Link to comment Share on other sites More sharing options...

mattdavies Posted January 17, 2014 Share Posted January 17, 2014 What are the offset options ? Quote Link to comment Share on other sites More sharing options...
JDukesy Posted January 17, 2014 Share Posted January 17, 2014 I have them and mine are ET25 all round in 8.5 front and 10 rear. You will need the arches rolled though Quote Link to comment Share on other sites More sharing options...
Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 What are the offset options ? Seems to be only 25 or 35. Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 17, 2014 Share Posted January 17, 2014 That would be useful if I knew my existing set up Thanks though. 2JZ GE is 225 x 50 x 16 and 245 x 45 x 16 2JZ GTE is 235 x 45 x 17 and 255 x 40 x 17 Quote Link to comment Share on other sites More sharing options...
Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 I have them and mine are ET25 all round in 8.5 front and 10 rear. You will need the arches rolled though Hmm I may go for different wheels if they don't fit well without modification. Really I need to find out the offset of my current wheels as they're 18x8.5 fronts and 18x10 rears and the fit nicely. Quote Link to comment Share on other sites More sharing options...
Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 2JZ GE is 225 x 50 x 16 and 245 x 45 x 16 2JZ GTE is 235 x 45 x 17 and 255 x 40 x 17 Cheers, What is the width of standard TT wheels? Is it 8.5 and 9.5? Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 17, 2014 Share Posted January 17, 2014 Cheers, What is the width of standard TT wheels? Is it 8.5 and 9.5? GTE are 8" and 9.5" Quote Link to comment Share on other sites More sharing options...
Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 Right with an offset of 35 all round the fronts will stick out an extra 15mm and the rears 20mm than standard wheels. Would this require any modification? Really I should just go measure the offset on my wheels, hopefully it won't be raining later when I get a chance.

Dnk Posted January 17, 2014 Share Posted January 17, 2014 Wont it be 15mm for the front and rear if the offset is 35 front 35 rear Quote Link to comment Share on other sites More sharing options...
mattdavies Posted January 17, 2014 Share Posted January 17, 2014 a 10" rear ET35 will fit without modifiation Quote Link to comment Share on other sites More sharing options...
Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 Wont it be 15mm for the front and rear if the offset is 35 front 35 rear Must of done something wrong it's now saying 21.4mm for both, does that sound about right?

Dnk Posted January 17, 2014 Share Posted January 17, 2014 Must of done something wrong it's now saying 21.4mm for both, does that sound about right? Well the way i understand offsets is If the stock offset is 50 and you change to 35 then the wheel will stick out 15mm further, makes no difference whether its on the back or the front, if the numbers are the same then the difference will be the same Quote Link to comment Share on other sites More sharing options...

mattdavies Posted January 17, 2014 Share Posted January 17, 2014 You will be fine. I would fit them and then see how they sit before buying tyres. If they are near the edge of the arch then just run 225/40 front and 255/35 rear, this will give you a little clearance tyre wise Quote Link to comment Share on other sites More sharing options...
TuneR Posted January 17, 2014 Share Posted January 17, 2014 a 10" rear ET35 will fit without modifiation Front 8.5" et35 will no problem as well, as long as you dont go and stick huge tyres on. Standard 235/255 would be fine. Quote Link to comment Share on other sites More sharing options...
Gretie22 Posted January 17, 2014 Author Share Posted January 17, 2014 Awesome thanks guys Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 17, 2014 Share Posted January 17, 2014 My figures are if you fit the same width rim and just change the offset, obviously if you are fitting wider rims then you have to add that figure into the equation Quote Link to comment Share on other sites More sharing options...
Dnk Posted January 17, 2014 Share Posted January 17, 2014 (edited) For example, the fronts are 8 with 50 offset and you now fit 8.5 with 35 offset so the maths are 15mm for the offset differance and half of 0.5" (12.7mm) for the wider rim which is 6.35mm which added together = 21.35 if we are being properly accurate The rear is the same with the offset still being 15mm and the wheel is wider by 0.5" (12.7mm) so half the 0.5" (6.35mm) and add to the 15 of the offset which = 21.35mm Edited January 17, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...

Think I'll go with et35 Quote Link to comment Share on other sites More sharing options...

Think I'll go with et35 Ignore what it has now and just work from stock sizes as you have done then you can't really go wrong Quote Link to comment Share on other sites More sharing options...
