Here is a thead where Rambo installs the Legendary Rallye covers and makes several comparisons between them and the TMI covers. Also the end user gives his review. One thing I have noticed. All user complain the foam is too stiff on all rally seats. Rambo does make a great recommendation. He suggests using an ACI bun for the ass section and just using the bolsters from the rally buns. Problem solved.
The better solution is to just buy an extra set of repop seat tracks, cut 3/4" inch out of the legs and weld the feet back on. I've had several customers do this and then be 100% happy with the seats after that.
I'm late to this conversation- but thats ok because I was also really early to it!
I had procar rally's back in Y2k in my 69 elcamino.
I found them to be an awesome seat- although even with the seat at the lowest of the 3 positions it was still a tiny bit high IMO, though after a year of use they did settle a tiny bit.
The bolsters took some getting used to getting in and out, but man once you are in those things, its like you are in a slot car. I took the car on several multi hour roadtrips and they were excellent.
The only thing i didn't like about them was that the seat backs were so much shorter vs stock buckets. nearlty 2" lower. I understand procar is now selling a taller back version, and wider bottom version- Both probably good improvements, though the original really wasn't bad.
I didn't have any issues with the brackets or sliders- though it is worth noting they make 2 versions, one for FACTORY BUCKETS, which assumes you already have the factory brackets/stands welded to the floor... the other version is for factory bench seat cars, the outer feet will fall over the factory holes, and then you drill the inner ones... the angles and what not are corrected for NOT having the factory brackets/stands.
Had to really dig for this photo... taken in 2001!
