Scott TMN Posted September 12, 2013 Share Posted September 12, 2013 Hi guys, Looking at getting some wheels. Either Rota Grid Drift or GTR's. I currently have a set of MPSS waiting to go on 245/40/18 I think I'll go got 9.5j allround, maybe 10 at the rear? My question to you guys are what kind of offsets will get me the best fitment without be use if spacers, obviously I will have a bit of stretch so this should give me some leeway? Iv read a lot of people go for 20mm spacers front and 25 back to give a good fitment on standard wheels. I have tried to replicate this with offsets on the Rotas and got Rear: 9.5j et 20 Front: 9.5j et 30 Although this gives me 19mm less inner clearance on the front will this clear the calipers? Alternatively I can go for: 9.5j front 10j rear et20 alround but this means the fronts are extended 29mm. Is this too much? Sorry for all the questions, been wrecking my brain trying to work all this out haha Thanks in advance Quote Link to comment Share on other sites More sharing options...
KyleR Posted September 12, 2013 Share Posted September 12, 2013 9.5 front 10.5 rear with et 20 all round is the perfect flush fitment. 1 Quote Link to comment Share on other sites More sharing options...
Scott TMN Posted September 12, 2013 Author Share Posted September 12, 2013 Cheers mate, how will 10.5 be with 245 tyres on though do you reckon? Too much stretch? Cheers Quote Link to comment Share on other sites More sharing options...
KyleR Posted September 12, 2013 Share Posted September 12, 2013 Too much stretch for my liking. Most people go for those sizes in 19's with 245/35 front and 275/35 rear, I think 245/40 and 275/40 are normal for 18's, but don't waste money on little wheels, sell the mpss and buy some 19's Quote Link to comment Share on other sites More sharing options...
Scott TMN Posted September 12, 2013 Author Share Posted September 12, 2013 as much i would love to thats not really an option for me (£££) agreed i think it might be a little too much stretch at the rear, maybe 10j with et15. Should only give 1mm less poke? Quote Link to comment Share on other sites More sharing options...

Scott TMN Posted September 12, 2013 Author Share Posted September 12, 2013 I really cant afford to do that Quote Link to comment Share on other sites More sharing options...
KyleR Posted September 12, 2013 Share Posted September 12, 2013 It's £100 difference for the rims and maybe £50 or so for the tyres, sell the mpss pair for £250 and wait til next months wages come in Quote Link to comment Share on other sites More sharing options...
StevoD Posted September 12, 2013 Share Posted September 12, 2013 (edited) as 9.5 front 10.5 rear with et 20 all round is the perfect flush fitment. With a lil drop 245-35-19 front 275-35-19 rear but this set up does disturb the VDC, stick with 245-40-19 front if you dont want that issue Edited September 12, 2013 by StevoD Quote Link to comment Share on other sites More sharing options...
Scott TMN Posted September 12, 2013 Author Share Posted September 12, 2013 Thats got me thinking so Ive been doing some maths. Well my mpss cost me £550 for the set of 4. (each have 7mm+ tread) plus 18" rotas are £900 total £1450 whereas new tyres (Goodyear assy 2) are £748 19'' rotas are £901 total £1649 plus the loss of selling the current tyres 18's are a stretch as it is :'( I cant do it godammit haha Quote Link to comment Share on other sites More sharing options...

StevoD Posted September 12, 2013 Share Posted September 12, 2013 StevoD your car sits amazing btw! whats this VDC stick issue? As the rolling radius are different under higher speed turning it brakes the outside wheel If you run the 245-40-19 and 275-35-19 the rolling radius is about the same and causes no issue Quote Link to comment Share on other sites More sharing options...

As the rolling radius are different under higher speed turning it brakes the outside wheel If you run the 245-40-19 and 275-35-19 the rolling radius is about the same and causes no issue 245/35/19 is 0.91% smaller diameter/rolling radius than oem 225/45/18, your 245/40/19 are 2.88% larger. The 275/35/19 that we all run on the rear are a mere 0.44% smaller. OEM difference between front and rear is 2.73% larger at the rear. 245/35/19 - 275/35/19 difference is 3.21% larger at the rear, only 0.48% out. What you are running with 245/40/19 and 275/35/19 actually has the front tyres 0.59% larger which is completely wrong Are you sure those are the correct sizes and you didn't mean 255/35/19 front? That would give a 2.12% larger rear which would be fine. Or running 18's with 255/40 and 275/40 which would be a 2.42% larger rear, 0.31% out which is about as close as you can get?

KyleR Posted September 13, 2013 Share Posted September 13, 2013 Thats got me thinking so Ive been doing some maths. Well my mpss cost me £550 for the set of 4. (each have 7mm+ tread) plus 18" rotas are £900 total £1450 whereas new tyres (Goodyear assy 2) are £748 19'' rotas are £901 total £1649 plus the loss of selling the current tyres 18's are a stretch as it is :'( I cant do it godammit haha Right i've got a fix for this. Still have the sell the MPSS though Take a wee look in the FS section and you will find a beautiful set of Linea Course Dyna rims with rubber for under a grand. Granted the rears need replaced but the fronts are pretty decent at over 5mm. If you sell the MPSS for say £400, you only need to find another £580 to buy these. The rears will last another few couple of thousand miles to let you save further for replacements Quote Link to comment Share on other sites More sharing options...
Scott TMN Posted September 13, 2013 Author Share Posted September 13, 2013 Yeah I don't think I want this VDC issue haha An as good as the above suggestion is I want Rotas lol In bronze too So we think 9.5j et20 front (245 tyres) and 10j et15 rear (245 tyres)? The lower offset will compensate for the 1/2 inch less width? Quote Link to comment Share on other sites More sharing options...
aidan Posted September 13, 2013 Share Posted September 13, 2013 I have 245/18s with a 9.75 rim and stretch isn't noticable (to me anyway). Think you'd get away with it on a 10 rim, although might need lowering However, wheel widths vary from maker to maker - one 9.5"rim might be slightly wider than another manufactures 9.5" rim. Also tyres vary in same way from different manufactures - one listed as 245 might sit wider than another. Quote Link to comment Share on other sites More sharing options...

Rim sizes/offsets are good, but don't go 245 all round, go 255/40 front and 275/40 which is the closest to OEM sizes I think you can get. alternatively 245/40 and 265/40 will also work and may be a bit cheaper. Wait? You've already bought the tyres, did you buy 4 245/40's? Quote Link to comment Share on other sites More sharing options...

Wait? You've already bought the tyres, did you buy 4 245/40's? Ok that's good cheers, think ill go for that setup. And yes I already have the tyres, in a roundabout way that's what I now have. Tread on the standard ones are getting a bit low now so feel time is ticking a bit. I'll go with that and then maybe down the line a bit up the sizes on the rears? Or would you recommend 9.5j alround, lower rear offset to compensate? Quote Link to comment Share on other sites More sharing options...
KyleR Posted September 13, 2013 Share Posted September 13, 2013 As long as you have one of the staggered tyre sizes I mentioned it'll be fine, but the car will burst into flames and kill you if you run a square set up. I wouldn't go 9.5" all round, with staggered tyres it'll look a bit odd with the front stretching a little bit and the rear not. Quote Link to comment Share on other sites More sharing options...
docwra Posted September 13, 2013 Share Posted September 13, 2013 Best bet to avoid VDC issues = disable that bad boy. If you ant really nice fitment then Id take what Kyle has said and add 10mm all round, but youll need to get your arches rolled first Quote Link to comment Share on other sites More sharing options...
Scott TMN Posted September 13, 2013 Author Share Posted September 13, 2013 Ok cheers guys. So thats a no to 9.5j all round, but unfortunately i have to use my 4 245's. So I shall go with: 10j rear et15. This will extend by 37mm (1mm less that your 10.5j et20 suggestion) 9.5j front et20 - this will extend by 29mm Least then the wheel widths are staggered so room to change tyre width at the back later, and till then the rear will have more stretch than the front think im finally sussed and happy.
