Hi , I recently bought a 1998 Z3 , but having never owned a BMW or driven a rear wheel drive it's all new to me. Want to get it looking and handling well.

If you have never driven a RWD don't rush it: the Z3 is a lady that wants you to take your time with it, or you might get spanked

Hi Shaun and a great place for your answers what model did you buy any pics ? We like pics

 

[shaunsas]

1998 2ltr petrol

Very nice great colour not than i'm bias or anything

 

[shaunsas]

I put 18" wheels on and admittedly the wrong profile tyres..45s . Going to change them to 30s , will this stop the slight rubbing of inner arch when in a slight adverse camber ?

I imagine so i thought when i looked at the pic that is was possibly on 19's
Im on 18's
Wheels are 8.5j and 9.5 j i have 225/40/18 front
And 255/35/18 rear.
The height of the tyre may be causing it an issue as the profile may be causing the rubbing, normally there is room what are the wheels widths and offsets do you know ?

They are 8.5 on the front and 9 on the back 225 and 255 rear , put straight on

Is it the front thats rubbing ? Are the wheels flush to arch ?
Sounds like tyre profile its about 13mm larger over all than stock so its probably your issue

No it's the rear rubbing, could it also be a combination of the springs being old and spongy?

You just have too much tyre in the arch i think its about 15mm bigger to the rear .
If its lowered and the dampers are not great it will possibly catch at the rear of the back wheels as the liner kicks out slightly as it gets near the bumper.
Mines was lowered 40mm odd and caught abit on the correct tyres.
The springs shouldn't be causing it unless they are laz. Its more like the dampers arn't damping, alot of zeds are still on their original dampers no leaks but when removed have no rebound at all and this could be making the back end feel alittle loose.
With the tyres being wrong it may be catching more than it would if the dampers where more efficient.
3 bolts remove the rear dampers one at the bottom and two up top It may be worth checking how they are by removing one.
