We as enthusiasts have a pretty good track record of taking good cars and turning the ride into junk. The quest for lower lap times is going to take its toll on comfort, right?

Our BMW M235i recently received a track-ready MCS suspension courtesy of BimmerWorld plus Ground Control camber plates. A few days after the install we drove the car up to Pinehurst, North Carolina, for the Pinehurst Concours. Figure it’s a thousand-mile roundtrip.

Yes, there is some more NVH. The biggest noise comes from the front suspension during tight turns at low speeds—like when parking—as the front springs clank about. At slow speeds, and with the radio turned off, we can hear the rear shock absorbers compress and rebound.

Considering that this is a track setup, though, the ride isn’t too bad. The car doesn’t porpoise, tramline or do anything weird. We were never overcome with the desire to punch the person who valved the dampers.

If faced with taking that same trip next week, we’d again reach for the BMW.

Why are the springs clanking about?

Because race car.

Okay, let me get a better answer.

Something different. We have been eying their products for a while, and this application looked good for us.

I mean, that would be an acceptable answer as far as i know. I've never had a suspension that pimp on a car before.

But then i've never had springs clank about, either.

It might be a bushing. I'm just the test driver. Let me get you a real answer.

Update: Jay at Ground Control wants us to recheck a few things on those camber plates.

Every car I have lowered has not had clanking issues. I would get that checked ASAP you don't want something binding up or damaging the new parts. Never mind actually breaking something while in motion.

It's clunking around because there are no helper springs to help keep contact with the road under droop conditions.

Jay thinks some grease may have been wiped away during installation. We're only hearing the noise during very tight turns at slow speeds--like when leaving our parking lot. Otherwise it's fine. The car was fine during last night's track event plus the 5-hour roundtrip drive.

I somehow doubt that low speed corners would exceed the droop travel.

You'd pretty much have to have Hazzard County hang time for that to be a problem.

I'd still want to get under there.
