Here's my '91 close to the time I got the car in 2002. The only changes to the car at this point are the addition of the roll bar and painting the vent & trim rings red.

Here it is pretty much in current form. Added:
Rage Race 15" rims
Painted the wiper arms (they were badly faded/wind stripped)
K&N Panel filter
Borla muffler + 2.5" catback pipe.
Koni Sport adjustable shocks

The paint on the mirrors was fading badly, so I re-painted them.
Old then new:

Brakes needed upgrading too. Right rear caliper was frozen when I took it off. Lots of "Hammertime" to get the bracket to rotate up enough to take the assembly off.

The difference in size of the rotors from the 91 to 94 models is amazing:

Added braided stainless steel brake lines and put 1200 degree hi-temp paint on the calipers & brackets.

Front & Rear:

Have also added Racing Beat Street springs. Will post pictures once I've moved the rear strut perches down. Apparently my old springs had collapsed to the same height as the RB springs. I moved the perch to the top mount for the RB's, thinking I didn't want to ride all the way on the bump stops. Pictures soon...
