Maximum offsets on rolled arches


SupraDan24

Recommended Posts

I see alot of threads asking whether certain offsets will fit stock arches, but don't see much about rolled arches. What's the maximum you gain you could expect to see from rolled arches, i think i've read 15mm somewhere before? If 15mm is the case, what would be the lowest offsets capable on the front and rear for the following:

 

For every half inch in width, does the maxium offset decrease by 12.7mm?

 

Front

 

8j:

9j:

 

Rear

 

9j:

9.5j:

10j:

10.5j:

11j:

With sensible suspension settings and tyres that fit the wheels 9" +35 and 10" +35 fit well with rolled arches.

 

Use the offset calculator to work out the difference for other width wheels.

I can work out the difference in mm of the offsets no problem, its knowing whether it will fit or not thats bothering me. I know 10" ET35 will fit rolled Rear arches no problem, but how much further could you go ie will say 10" ET25 fit, or 9" ET25 on the fronts.

ET25 will fit if you want to stretch the tyres, I had a 10" et25 on the V8 supra but i could only get a 265 tyre on it.

 

10"ET35 with a 285/295 tyre is the perfect fit imo.

 

Cheers Jamie :thumbs: Thats disappointing though, i'm looking at some wheels in 10" et25 but ive got some 275 Avons sat at home ready to go on :(

 

mark p is running an 11.5" wheel on the rear on his with just an arch roll, I'm trying to find out his offset but they are off for a refurb :)

They must be ET50 or something. Could they be stretched OEM wheels maybe?

Marc (AB10) runs 18x9.5 +24 up front and 18x11 +22 at the rear. Stock arches with a roll.

 

Think the fronts may be pulled too.

 

Wow, that is quite some roll on the rear. I'm convinced i can get a 18x10 +25 on the rear now then, just have to hope my wheels sell so i can make an offer the other set i'm watching. A nice set of deep dish bling wheels win finish my car off nicely :)
