I need help with adapters

[VR6child]

I have a set of wheels, 8" fronts and 9" rears. They have the porsche bolt pattern (5x130) so I'm buying adapters to make them 5x100. Rear ET is 36, front ET is 62. If I remember right I think the stock VR wheels are ET 42. Can anyone tell me what width adapter I need to have these fit and clear the suspension/calipers etc while poking as little as possible? Tyre size advice is also welcome, I'm guessig 205/40/16 for the front, but for the back I'm not sure. Will I need 1 degree negative camber for rears? Putting 205's on a 9" wheel is pretty extreme stretch right? It might be the only way these will work though. Any advice about any of these questions appreciated.

Front will fit easy. You want max 32mm adapters on the front to make it 8" ET30 - this will have the wheel sit flush at best. I wouldn't go thinner than 25mm adapters for the front, or you will run the risk of rubbing on suspension. I'd recommend 195 tyres to help clear the suspension and the arches. It may not carry the recommended speed/load rating but many others in the US with VR6s run stretched 195 tyres without any troubles.

Rears though... you'd want the thinnest adapters you can find. Thinnest I've heard of are 15mm. In my quest for finding the thinnest adapters, some Americans have pointed me to Alloys R Us. However they're US-based, so cost will be far from the best. A fellow member here has told me he could make 19mm adapters, and for a very good price. If you choose to run 19mm adapters, your rears will be 9" ET17, which is a very good offset to work with. Should clear the suspension, but will poke a little. With 205 tyres (215 max) + rolled guards, you'll be set. Shouldn't have much trouble with rubbing unless your dumped and tucking tyre.

For some reference...

The fronts are equivalent to 16x8" ET20, and that has just a bit of poke with very little camber. ET30 should be just a little inside the guard. 195 tyres will mean less rubbing when attempting full-lock. Rears on this car is 16x9" ET11. ET17 would just mean 6mm less poke, which will still make it poke, just less. Don't know what the tyre sizes are for this pic, sorry:


16x8" ET32 on the fronts:


16x9" ET18 with 205/40R16 tyres. Camber isn't that large here, it's the angle of the shot:

You can definitely put the wheels on, but you can't take shortcuts if you want them to work.

I love this site, thanks a lot for the input that spells it all out for me. Vortex isn't that great for technical info. I just couldn't do the maths on the adapter with it was driving me nuts. I'm leaning towards 205 front 215 rear which I think could work as long as I have some wheelgap. I've seen 25mm front adapters run with these wheels and I want that size but if you're talking about mm of clearance, I guess it will depend what model suspension you run. What clears for one brand of suspension might rub on another. Again thanks for the input I'm gonna keep researching but this is a big step in the right direction.

rays on the money here (nearly :p), i run 17x8 et25 and I reckon i can still get away with another 10mm which would make it et15, I do run -3deg camber though. for the rear you will poke, only slightly so as ray mentioned get the thinnest available being 15mm. Now where's our rim pics!

:edit: oh, and run 215 on the 9" rear, its an extreme drivable stretch, you'll get non-stop comments though on how "funny" and "i'll-fitting" they look! hahaha
