Noel,
I've got the S121 steering box. I don't remember the IROC one being available at the time (about 3 years ago). If it had I might have ordered it. I also remember mine being rated at 2.9 turns lock to lock. Not important but thought I'd mention it. Bottom line for me- it's worth the money which is how I evaluate things that I do or buy. I'm an old biker and for me driving is about the curves. Living in east Tennessee we've got plenty of them around here and driving through these hills is DEFINITELY more fun with a close ratio box. Having all PST front end plus all Hotchkiss equipment front and rear and KYB shocks all around makes for the majority of the improvement in handling, but that close ratio box lets me enjoy it. Hope this helps you.
Bob
