Lowering Spring Advice Needed!

Nightmare sounds a bit dramatic. One doesn’t stick 18’s on a car that originally came with 14’s without expecting to tinker a bit. There are several forum members running 18’s. I think the limited number of e9’s on 18’s has a lot to do with owner preference and little

18" wheels will be a nightmare to fit and make your car ride like sh1t. To retain some ride compliance 16" is the largest rim size to go for.

My car has a Carl Nelson front end - as above he shipped to the uk. Expensive but worth it.

Fitting wont be a problem but I agree with you driving quality will be worse. I drove it with original 14" and it drives nice smooth and nice through potholes.
But on other hand I think I will be doing max 1000 km with the car per year...

Assuming that you are referring to factory 18” BMW (bbs) RC061 and RC062, I don’t believe that you will have fitment problems with rolled fenders and some tire stretch. The 8” fronts are ET20, same as the 17” version that is successfully run on several member cars. The 9” rear are ET24. Vince is running 17x9 RC’s at ET26 on his e9 and they clear the fender and the suspension. You would be 2mm closer to the fender and it will be a bit tight. You will probably want to research tire brands that work well with tight clearances.

You are correct. Front needs spacer to get inside clerance but not to much in order to keep wheel under fenders. Will try to find tires 205/40 for front 8J and for rear 9J 225/40 will be just fine. I will leave fenders like they are original in case wheels will rub I will change them.
