Hello. Got a Z3 2.8 1997, awsome upgrade from my 1.9. Luck has it it is the same color.

And if i may ask for some help:


1. What wheels are these ? They are 18" with 225/40/18 all around but that's all i could judge.

Measured the rims. All seem to be 9.5". Am i doing this right?

So 18" by 9.5. 5x120 bolt pattern right?
What's left - the center bore and the ET.





2. I noticed a discrepancy gap on the back drivers side wheel vs the other one - one is inwards more than the other ?! Is this normal?

3. So that's why i am interested in spacers.
I want on the back to have the wheels flush and put wider tires on the existing rims but within reason.
So spacers plus 245s on the back on the current rims, would be an ideal setup that will not have negative effects on handling etc?





4. Something like this are any good? Of course when we find out what size i need.

5. How do check if i have an LSD ? Decoding the VIN it says that but i want to physically check.
Tags on the diff?
Lift the car up and the wheels should spin in opposite direction?



Thank you in advance.
