How much of a difference is 18s vs 19s in the rear? I would personally like to keep 19s in the rear for the look, but if it makes a big difference it's not something I would want to do.

 

I switched & I hook up much better with the 18's than the 19's. "spinmonster" has a whole write up & comparison on this topic. Just do a search.

I didn't want to get rid of my 19's either but. I need the most traction possible & with a 35 profile tire the overall wheel size will be the same as you 19" with the 35 runflats.

Also yourC6/Z51 rotors & calipers wont look so puny with the 18's:-)

I dont miss my 19's at all!! My car has never looked better!!!

 

Was it an upgrade over the regular sway bars, or Z51 sway bars?

 

I went with Hotchkis Sways. They are a HUGE upgrade over the stock c6, and are advertised as an upgrade for Z51 owners as well.

But there are many other alternatives. I have 3 stiffness settings on mine.

 

I have come to grips with the fact that my 19's will have to go soon.... With an 18" rim in the rear it will allow for more side wall, which in turn will result in FAR better traction.

With the power level I'm shooting for in the next couple months (600rwhp) I don't think I will have to go wide booty just yet. I will be ok with a 305 M/T in the rear under the stock fenders for now.

The wide booty looks great! I think I would rather dump most of that money into more performance. For me since I can hook up with 305 M/T's, under the stock rear quarters - the wide booty would be pretty much just cosmetic.

Decisions, decisions - all this crap is driving me nuts.

 

I dont think you can find a 305/19 in a 35, just a 30, so they will be a little small looking in the wheel well. When i had mine, I lowered the car a little to compensate. They still looked small though but it's not the end of the world. Running lower tire pressures help hooken up as well.

 

I was referring to an 18 inch rim in the rear, with a 305 M/T.

I just can't bring myself to spend 4k on that modification, after new rims, tires, fender package and labor - it's right around 4k or so.

I bounce back and fourth everyday.... One day I say the power I have is enough for a street car/daily driver..I should do the wide booty, it will look bad *** with the wider wheel base and wider tires.

The next day I tell myself, my car isn't fast enough - Spend the money on more power, I don't need to spend 4k just to have the car look better.

What do you guys think?

 

I would take a break from the forum before your head explodes....Been there so many times:-)

What's your current HP & TRQ to the wheels? Do you have any intentions to increase it in the next year or so?

 

He is looking to go from 490RWHP to ~600. 490 isn't confirmed on my end, but I'm pretty sure he is close to it.

Mike, my Dad's Vette runs at around 650RWHP and he runs a D/R set up on 18s (17s in front) with a 345 on it and has MAJOR traction issues. Keep in mind that's just a whopping 50 more RWHP, which at that power doesn't make a tremendous difference. He breaks loose and fish tails punching it at 100mph. That of course is with his boost at half.

Mike I know money into power seems like money well spent, but keep in mind that power is worthless without putting it to the ground. Find someone with a similar set up and PM them and ask their opinions. You won't be happy if you get more power and can't use it. Keep in mind with nitrous you can't control the power so when it comes in all at once you may be struggling to maintain control of the car, I know my Dad's has gone sideways a lot because the boost keeps coming in and it's very hard to control.

EDIT: Not only that, but you will spend the money on a stickier/wider tire now, then up your HP #s and then HAVE to go with a wide body at that point anyways, so if you do it first you will help your traction issues now and enjoy it, then when you get the power you won't have to deal with it.

 

Upgrading Traction doesn't seem nearly as S-E-X-Y as adding more power, does it.

Hey, I didn't think i'd be spending so much on traction either! It's a lot of bucks when you start playing with F.I. But I'm "All-In" at this point, can't turn back now......

 

I have a set of grand sport wheels tires and sensors mounted and balanced with 550 miles on them- considering selling them. Let me know if your interested.

I want to do a wide booty conversion I plan to put 20's on the back and 19's on the front what sizes tires do I need to get proper clerance i dont want the front tires to stick out the fenders and were do I find prepainted rear Z06 fenders and how much do they cost

 

When you still haven't hooked up at 80+MPH with 500+ rwhp on stock width rears, you'll understand the need for wider rubber and hence the wide booty conversion.

 

The only stress is on the adapter itself which is the strongest metal on the car. Guys have run this without issue. The adapter plus the stock widened rim weighs less than after market garbage.

To answer the OP's question, a 1 3/4 to 2" will work for the adapter size and it has worked fine for many forum members. 2" puts the edge of the 19" rim close to the limit of the fender. A 345 tire on a 18x12.5 with a 1 3/4 is the limit for a widened 18 and the 19 widened to 12.5 to work with the 345/19 nitto can use the 2" because the 19 sits a little further inside the wheel well.

Traction is better with more sidewall so the MT ET street on the 18 is better.

The 19" with the NT05r looks great and lasts longer in that its a 00 compound with 6.3/32s to start life at. A 305/18 MT on a 18x11 is better than the 345/19 nitto for traction. A 275 on a 17 is better yet. You have to decide if bling is more important than performance. The C5R and C6R run 18's all around.

 

I put the wide body kit on and bought the spacers to use until I ran the tires off. Worked great for 20,000 miles. I've just bought the wide wheels and have two 19x10 chrome Z06 style wheels and 1.5" spacers for sale.
