Va MX5 wrote:Folks, this is my 1st post on this forum, so, Hello to all. The folks at Goodwin Racing have been an excellent resource and a great vendor to work with, even with some of the challenges I have caused them. I am interested in this thread and the SS project because its base is a PRHT. I picked up the Progress springs and sways, along with a couple of other things, from Brian. Current plans are to use the factory Bilsteins with the new Progress springs until some other things are improved on the car, and circle back for good coilovers later. Parts are in the shop and install will soon begin. The Progress instructions supplied with the springs indicate one should cut the Bumpstops by 50% as part of the install process. I have read some of the posts by Az Sun Lover, FrankP885 and Chuch H on the bumpstop subject, understanding their comments are in the context of Koni’s / Progress springs / bumpstops. Also read references to FCM bumpstops (not familiar with these), as part of the ongoing exchange. Great discussion guys, thanks.
Question for Brian, what bumpstop did you use on the SS project and did you cut the size as part of the final install? If so, by how much?
On another subject, while I have the car up in the air for the suspension upgrades, I was thinking of installing the RoadsterSport Street Header, Brian has developed. Brian, do you have any of the Ceramic units left in stock? In some of the thread comments you had referenced efforts to “avoid codes”, is there any issues remaining in that regard? Also, would this Header be suitable for a super charger upgrade in the future, that would likely pass “49 state” requirements?
I am new to MX5’s and I am enjoying the car, particularly as the setup improves. Two things about the car I would like to do something to improve, are 1) lessen the road noise with the top up, and 2) find a Much Smaller rear view mirror that works with the factory mount. I hate losing the auto dimming and door openers, but the loss of visibility is worse. Anyone’s thoughts would be appreciated.
