Miata steering rack
 

I have been told that a Miata de-powered steering rack is a great mod to do to my FD3S.
Any one had experience with this? or have any opinion on this?

I've done it and did a write up that's now in the 2nd gen archives, but there's a better writeup here that includes the welding of the pinion shaft: http://forum.teamfc3s.org/showthread.php?t=54847

This has been done to many FD's by Mavel Gear and if you search you'll find some reviews and so on.

Thanks. I was going to use the miata rack @ 15.3:1, should be great for the track. Any one used a miata rack?

What kind of car do you have? I wouldn't think that you can just swap the rack and have it fit, it'll probably require some fabrication. Besides, the FD and the S4 and TII power racks from FC's are all about that ratio anyway, so if you've got one of those, just de-power the stock rack, or if you've got a different FC, get the power rack from any S4 or an S5 TII.

Followed Black91n/a's thread to a T and my FC rack works great in my track car.

Yea that sounds like a plan, be easier than using the miata rack.
