My vert is headed in this week for subframe reinforcement, bushings and wear items associated with dropping the subframe, and upgrading to the Koni/Eibach setup. Looking forward to putting some miles on it this summer after the refresh.

Note - this is not a knock against 'verts, just pointing out that the 'vert chassis won't be able to absorb (as well) higher loads presented by an aggressive suspension, thus resulting in a less pleasant in-cabin experience (which is what the 'vert is all about).
Good advice. If I had it to do over again I wouldn't buy the KWs for a vert. The extra pounds in the rear was not accounted for by KW. My KWs are at max recommended height adjustment and sit a little too low for my liking but I can't adjust anymore. Pisses me off and pisses me off that I didn't do a better job researching. Once I realized my error I found a few other threads where e46 M3 convertible owners with KWs experienced the same issue.

If you're not off by too much, maybe try thicker spring pads?

I have an 03 vert. I went from 20" stock rims to apex arc 8 18". Euro downpipe and cats, tuning tech tune, I think that's it.

I would really like to upgrade the headlights. Will have to research what some of the others posted and try and find a parts list.

Suspension refresh at some point too.

Thanks for starting the thread.

I'm dumb. LoL. I didn't realize there were options. After reading your comment I've looked and that will work. Thanks man.

I'm sending the wheels off to get refinished, and the car is ready for some suspension love over the next couple of days...
