offset calculation help

Recommended Posts

Hi guys just bought my VR to replace the lupo tother week and i am looking at some wheels.

BBS RS they were 7" ET35 previously and the owner now says they are 8" with an offset of ET25 but an inch is 25.4 so shouldn't it be ET10 with the additional inch? Also it has 17mm adaptors so i make the total ET-7.

Am i right?

Here's a pic of my vr anyway lol

he is about right et drops by around 6mm for half inch. so 12mm for an inch givs offset of et23. using the offset calc though it comes up with et22 so its not exactly 6mm for half inch lol. et 5 with adaptors in place.

use this badboy to check.

rs is handy as it can be changed to suit the car as its a three piece.

Yeah, I agree with that. et22.

Offset is measured from the middle of the wheel so it's only really half an inch extra.

I think. :wacko:

ET is measured with mm so If you have a 17mm adaptor on a wheel with ET25 you'll got a "real" ET08...!

That's theory,I don't know if that right but I do that mod to know what I got for mine Cup's...!

;)

Cheers,
