GT4 Clubsport Maintenance, Updates, and Issues Thread
I would like to start this thread asking all those owners of Clubsports to share their experiences with the car from a technical perspective. I am a new owner to the car and my car had about 900 miles on it when I bought it. It has been incredible to drive and own. I recently installed new brake pads and some new tires. During this time I noticed my rotors were beginning to show some cracking and signs of fatigue. I have asked Mooty for any info he has on maintenance on his car and he has gladly shared. I live in the NW and there are few of these cars around. I can do some DIY, but not a whole lot. I would love to see this thread grow with information and advice for owners of this great car. If you are an owner and have knowledge of issues, tips and tricks or other data relative to the clubsport, please chime in. As time goes on I am sure we will all experience some wear items or challenges with the car that would help give others insight in the future. Thank you in advance. I have attached a couple photos of my rotors as I am going to be purchasing some new ones. Mine have a few more miles on them, but I would like to have them ready. I also have new headers coming as well.

Maybe a dumb question, as I am, but your pictures look as though the rotors simply sandwiches between the hub and, presumably, the inside face of the wheel. There's obvious "slack," for lack of smarter word, between the wheel stud and rotor. How is the rotor indexed to concentricity with the wheel/hub assembly? I feel it's safe to assume the rotor doesn't "wobble to and fro?" Sorry for the post with zero add value.
BTW - your GT is stupid awesome. Possibly the best car built thus far - congrats

I dont know what the updates are. I bought the car with 900 miles on it and I think it has different shocks from stock. I have more suspension coming in from the previous owner as well as new headers. Still have a lot to learn.

Jlenox, you can see the screw locating the rotor right there amongst the studs.
cwc, you have lots of life left on those rotors. dont worry about a crack until it goes edge to edge. have a set sitting aside but i would not take those off yet..

+1 PFC rotors seem to crack a lot, but it's fine until you see something extend to, and exit the edge - or you have reach minimum thickness.

We have 5 Clubsports in our shop that we look after, 2 of which are MR spec cars; i get to drive them during the PCA enduros and we campaign one of the MRs in IMSA and i get to drive that one as well. You want the updated aero, catless exhaust manifolds, revalved shocks and different springs & rubbers, all of which you may already have. There's a bolt for the rear control arms with a shorter head that was issued because of concerns over wheel clearance and there's also a flange or "donut spacer" for the axles that you will want to run if you're running more than 3.5 degrees rear camber. There are bulletins for intervals for master cylinder rebuilds and i think that it's worth rebuilding the calipers every few weekends - 4 maybe? We have run the PFC pads as well as we have experimented with alternate pads compounds from another manufacturer. If you are striking out, if you call the shop and ask for Wray, we can get you anything you need for the car.
They're really great cars. It's a shame they arent more readily available but that's good for resale! Congrats!

Hi all, a new Clubsport owner checking in. I would be very interested in trading info on experiences with the car. I had a qualified shop go through the car I purchased, they offered up some good tips, but it's on it's way home and I'll certainly have questions as I get to run and know the car. Looking forward to that!

No plans for racing at the moment. I look forward to learning the car and driving at a couple tracks where I am a member and also whatever club days at different trfor PCA, BMWCCA, SCDA fit into schedules and such. I have been doing arrive and drive in my GT3 cars up till now, this will be a different thing understanding better after driving the car last Saturday. I think it will be fun and challenging.
