Save your money and forget the 17's...17" wheels and tires generally cost alot more money than 16's, 18"'s are even more $$$....People want to complain about the Torq Thrust II's??? I mean no disrespect when I say this but everyone having an erection over 17's or 18's on a first gen and then leaving the old grandma 40+ year old steering gear box in there makes me want to hurl!!
You want it to handle better? Put one of these in there from Detroit Speed http://www.detroitspeed.com/productp..._gear_prod.htm
Then mount some P245/50/ZR16's on it.....FWIW, I have that gear box in my car in the ceramic version....I'm debating the tires now because the car has other issues at this point, so I'm rolling w/ P235/60R15's all the way around on Chrome Rally's.
You will have spent less money putting that set up on your car along with that Detroit Speed third gen steering box than P245/45/ZR17's tire & wheel combo's...That 16" size is what the 5.7L IROC-Z's rolled with and both my third gens would eat either of my first gen's for lunch in a road race with lots of twistys back in the day or even today. Forget the $2,500 + tax 17" tire & wheel packages. I've even heard some guys say they spent $4,500 on 18's....Put a 3rd gen steering box in there with some P245/50ZR16's......That's less money overall for the 16" tires & wheels w/ the 3rd gen steering gear box, and you'll out handle the guy with 18's who spent enough money to feed an entire neighborhoood and wants to be cool, yet still runs the 40 year old gear box.
FWIW, The Tire rack has Z rated BFG's P245/50/ZR16's at $93 per tire brand new right now! The least expensive BFG in a P245/45/ZR17 size is $128 per tire.....I've seen P245/50R16's go for $100 for all 4 tires w/ 9/32" of tread on them that are three years old on craigs list in my area.
FWIW I like the 16" Torq Thrust D in this color..They are $230 per wheel and not $400 like some 17's I see.... (It's not made in a 17" size) http://www.tirerack.com/wheels/Wheel...All&sort=Brand
Too many guys in my area spend Waaaay too much money on 17" tires & wheels and even more on 18'" combo's and neglect the steering gear box.....The big brake kit will still work with a set of 16" tires & wheels. It did with the 1LE IROC-Z's & 16's. It will with a first gen & 16's.....
I have nothing against 17's...It's just that prices are rediculous on 17" combos and even more outrageous on 18" set ups....The P245/50ZR16's with a 3rd gen steering box will outhandle 17's & 18's and the 40 year old gear box. Now if you can afford the 17's or 18's, the 3rd gen box, tubular upper & lower control arm's, hey more power to ya!..Just trying to save ya a few bucks and I mean no disrespect.
