My Ride: 2002 330Ci
ST Coilovers with 18" Wheels

So I've set aside some money to finally confront my very worn suspension on my 02 330Ci w/ Sport Package. I've decided I might as well go with coilovers and hence i've been doing a fair share of research that led to me deciding on ST Coilovers factoring in reviews, recommendations, and pricing.

I already have a fairly aggressive wheel/tire set up for a non-m e46 so I wanted to run this by to see if anyone has a similar or possibly even more aggressive setup coupled with coilovers.

My wheel/tire set up follows:
Front: 18x8.5 et35 wrapped in 245/35 tires
Rear: 18x9.5 et45 wrapped in 265/35 tires


My worry is more towards the width and offset of these vmr v710s with the ST coilovers.

ST Coilovers Estimated Lowering Range (via Suspension Source):
Front: 1.2"-2.8" / 30-70mm
Rear: 1.2"-2.0" / 30-50mm

A few additional factors I was considering with this is having the sports package already has my car sitting a tad lower. Also, I feel like the factory springs with 160k on them are more than likely sagging. I picked up the car with 115k and prior maintenance is unknown.

With the height adjustment options of the coilovers, I feel as if I should be fine. Worst case, I am mentally prepared for rolling fenders as needed.

Thoughts? Similar setups? Did you have to roll the fenders?

Your setup isn't really that aggressive, but I do see a front wheel spacer in your future with Any coilover setup.

The ST setup is a good one, I'm going to make another suggestion though.

This setup offers a Tremendous value for the price:

Those are for an M3 unfortunately. The GC set-up is nice because you a) get Konis, and b) they use standard race springs, so for a very reasonable price you can get new spring sets if you want to try other rates or have one set for street and one for track.

These M3 suspension components will work on the OP's 330Ci Bimmer.

Hi Fo Show!

First off: the black V710s on your e46 look great! It's good to hear also that you are taking the next step in modifying by putting your car on a set of coilovers and lowering it.

I thought I'd chime in regarding wheel/tire fitment.

You're currently running:
Front: 18x8.5 et35 wrapped in 245/35 tires
Rear: 18x9.5 et45 wrapped in 265/35 tires
In our testing we show that our ideal sizing is:
Front: 18x8.5 ET35 with 225-235/40/18
Rear: 18x9.5 ET45 with 255-265/35/18

Running these wheel/tire specs should clear a lowered E46. There is two very important things to consider as well though:

How much will you be lowering your vehicle?
What will your alignment specs look like ( camber )?

The alignment specs specifically can significantly alter fitment.

I hope this information is helpful to you and helps you dial in that perfect look. I can't wait to see pictures of the finished product!
