Rockstar garage produces a lot of great products for the S2000 community. More specfic for the S2000 track community, as being the best place to get Buddyclub parts (cheapest in the nation) they have a wide range of safety stuff for the S2000 including roll bars, hardtops, seats, etc etc. I have been using their hardtop for the past 2 years.
This hardtop was one of their first prototypes so its a little rough in some places which is expected. The window is a little rough cut but it seals just fine and the tint is an awesome touch. I love the fact that it comes with a glass window that can be found many places (its a MR2 windshield). Now on to the seals on the window, which work well but the very edge does not line up with the windshield which was an easy fix (add more double sided tape on the bottom of the seals, kind of like a spacer).
Above are the non soft top mounts, meaning its mostly for race cars, the rear mounts (photo on the right) fit well no issues, no problems proper seal on the rear of the car. The front top latch mounts (left photo) how ever do have a problem. You have to install them by using a little force to keep the hard top leading edge down far enough to meet the windshield. (true pain in the ass) the allen bolts that go into the hardtop constantly back out even with lock tie on them so my next step is to add a locking washer to see if that helps. Other then those two things everything worked well.
Also you can see that I have no paint on mine, bad idea if you order save yourself the time and hassle and just get it painted from RSG. Save yourself time money and effort. I would recommend this hardtop to any NASA or SCCA member that needs an OEM hardtop it's lighter, easier to install and a great bang for your buck!
