    Getting some 18 bbs rs 9.5j on the back and 8.5j up front would i have any issues with hitting coilovers or would the rears actually fit, would i need spacers as well, and what would a sensible stretched tyre be? Cheers for your help.

    8.5's up front, you will need ET30 Minimum to clear front strut, ET25 will be ok too running 225/40s. There's loads of room in the rears, but not had experience with 9.5" wide. Running 8.5" wide, and ET20 on my car, there's still plenty of room, so I guess ET15-20 with a stretched tyre is fine, but someone else with experience may want to add to that.

    Okay thanks so your saying rears would fit without spacers, but fronts would need a spacer? I did think about running 225s how much stretch would i get a stupid ammount? Cheers jo

    Nono, you definitely need spacers on the rear, aim for ET 20-30 on the fronts, it really depends on how you want your car to sit? ET30 would probably look tuck'ish(based on lowered by 60mm), ET20-25 would fill the arches a bit more. I'm presuming if you space the front out, the rears will need spacing too. ET40 on an 9.5" rim is too low an offset, it will more than likely catch the shock absorber, ET25 is my guess for the rears minimum. I know ET35 on an 8.5" rim is fine on the rear, but it's close!

    Ahh what size spacer you reckon i would need im thinking 15 20mm rears then 10 up front what kinda fitment would that give me? I would want the arches filled and the alloys to poke a little haha, im really bad at this fitment thing :/

    If the wheel offsets are ET40 as you stated earlier, then you would need 20mm spacers to make them ET20, that's 20mm spacers each side. You need to know the offset of the wheels 100% before you start buying spacers, are you sure both the 8.5 and 9.5 rims are the same offsets out the box?

    If its helps I'm on 9j allround with 11mm spacers the fronts are close the rears have bags of room also running 215 30 18 tyres get a lot of stretch with them but I'm am rather low as 225 40 wouldn't fit the front without rubbing also cambered the rear wheels 1 and half deg to help with the tyres clearing the inner arch

    I'm running ET5 rear, ET10 fronts (to clear 6 pots) on 8.5" CHs with 225/40s and it's very slightly rubbing on the small plastic "ridge" on the rear on the rear (the "bump" you can feel with your hands) over big bumps. I'm not actually sure what it does other than hinder tyre clearance so I might look at removing it somehow?
