Offset Help!!

[Zizzle]

I dont have a scooby doo as to what offset means all i want to know really is...

will these fit my e30

7.5x18

4/100/

et 42

215/35/18

I need to decide on a set soon... so need all the help i can get... will be gettin FAT spacers too so that they give my e30 cab with m3 panels a low fat squat... or will they not be needed???

Thanks guys!

To correct the et42 offset on an E30, you'd need 22mm(ish) spacers.
That's before you take into account the M3 wings.

Far too much spacer required there IMHO.

****OCKS!!!

So need about 50mm spacers like on the bulldogs.. hmm...!!!

OKay whats the ideal offset that i dont have to do too much fiddling with... i just need to find big deep 4 stud rims... and its so damn difficult!!!

Cheers mate!

Ideal offset varies with rim width.
Taking 15" BBS as a reference point, they have 7" rims and et24.
Offset decreases by approx. half an inch (12mm-ish) for every extra inch of rim width.
So 8" rims are usually et13 on an E30 and 9" et0.
I'm not sure what the extra width of the M3 wings is. But I'd guess that 9" rims with 10mm spacers might just do the job you want.

Yeah thats what im after... but they are only availible in the smaller sizes... i was going to get 9x16 all round but i figure they may look a bit !

Do you no of anywhere i could get my hands on something???

Sorry Dude, I don't. It's not something I've ever been into.
I know all the theory, but I've never put it into practice.
