Quite a few forumites have ordered from Fat Cat Motorsports.

I had a set on my car when I was living in the US. They are great. The mounts though are very similar to the effect you would get by installing NB mounts. If you run NA springs you could lose some ride height (esp. in the rear).

I purchased some 46mm bump stops and red boots for my 1990 NA a year ago. No problems dealing with them, they answer emails pretty quickly, they lost my shipping address at one point. I think that these bump stops are great and are just a better economic choice than going for a stock bump/boot replacement.
I am running them with KYB AGX adjustable shocks and standard height king springs. My shock mounts are standard, but I did toy around for a while thinking about the fat cat shock mounts or trying to pick up some NA series 2 shock mounts.
My AGX shocks are set to a soft position 3 front and 4 back (8 positions) all round for normal every day driving, it drives nicely.
The height on standard king springs is naturally stock and most forum members want to drop an inch or so but I have been lower on bilsteins and RS*R springs before and I had speed bump and a driveway kerb issue's. Behind the front wheels bottomed out and the underside of the rear bumper has gravel rash from running about 30mm lower.

By the way the fatcat bumpstops are the same items sold by Ground Control for less.

Fatcat cuts some of them to length though...
