Does anyone have 20 inxh wheels on their non gfx firebirds, formulad, early ta's? I found some awesome wheels and fear 20s are too much. I could maybe see 19s front 20s being ok but these wheels are not available in 19.

Tnx

I dont see why not a buddy of mine has some on his 89 Iroc I can ask him what his offset is if you need to know

I know the required size, problem is...it may look like crap since I have no gfx

Looks are purely subjective - although even 13" brakes will looks rediculously tiny under 20" wheels.

But they are going to weigh a ton (20lbs or more lbs added per wheel), along with the very low profile sidewall is going to make the car ride horrible and also handle like poo...

I will have at least 14" brakes but most likely 15 or 15.5

I don't mind a harsh ride, the roads are pretty smooth here

I have no complaints about my iroc w/ 19s and low profile. My buddy has 20s under his GTA it drives and handles just fine..

I would worry about tire prices. Even 19" tires cost an arm and a leg, and that's for all seasons that last a long time.

I only tun ZR rated tires usually vredestein ultrac sessanta no all seasons for me

does no one have pics of 20s? Guess I'll have to grab 2 of the 20s off my buddies GTA and check for myself

You really don't need anything above 14" rotors for brakes along with 4 or 6 piston calipers - not like you can even get enough tire under the front to really use them 100% anyway...

It has been tested and proven in various media outlets that wheels above a certain size(depends on the car) hurt handling considerably, even if the "feel like they handle good". With the suspension design, tire diameter, cost, and wheel weight considerations, a 17" or 18" wheel is optimal for the 3rd gens in terms of maximum handling. Keep in mind that CTW Motorsports wheels in 17" x 9.5" clear the 14" 6 piston Baer 6S and C6 Z06 setups, as big as you would need in any street situation.

In terms of tires, there is a huge difference in handling between a base Vredenstein and say a Falken 615K in the same size. Of course in your area, you may not have as many choices as the folks here in the US...

I know, and I'm not interested in the discussion...I just want to see 20" wheels to get an idea how it looks and if I get wheels that size the rotor size is just to fill the wheel.

I don't want 17" wheels, they are played out, I had 17' wheels back in the early 90s...I want at least 19" because I think it looks better.

As for handling, there is a HUGE difference between the sessantaas and the cheap falken tires. Have a couple cars with Falken FK soemthing somethings on them, their highest rating tires... they can't hold a candle, especially in the wet. The Vredesteins are so much better. In fact, I feel the Vredesteins are better than the michelion pilot sports I have had.

I've never understood this mentality. Does that mean in the year 2020, we'll all be rolling on 25's, cause 20's will be played out?

Do you all have a problem reading? I asked for pictures, not for people wanting me to explain why I want what I want. I don't owe you an explanation.

If no one can show me a pic this topic might as well be locked dow. I don't feel like having to be stuck with all kinds of people who want to argue, second guess me or downright tell me I'm wrong for running large wheels.

PICS or STFU!!!

Homer23

I don't know, 20s are pretty big.

Don't go to 22s like a few guys did, or we will rain down the hate.

Podium

iTrader: (2)

I agree. I can't stand when people do that.

Also, 20s look stupid on a third Gen

Twin_Turbo

iTrader: (25)

My buddy has 20s on his 92 GTA and IMO it looks good, but the car has more "body" due to the GFX, I'm afraid on mine it will look like coach LOL

Those do look nice on there. I am concerned a 20" might be to much on a non-GFX car. Can you share the wheels you are looking at? Some styles look smaller than others. To me you can get away with larger wheels with a mesh style and/or a stepped lip.

Also, if you ever need to fill those big wheels with some brakes, I have a few good ideas!

This is a 19"

Twin_Turbo

iTrader: (25)

I have Z06 calipers, I just need larger rotors. That's why in your brake thread I asked about the 32mm wide rotors


These are the wheels I'm looking at

87350IROC

I forgot you have the Z06 brakes. You seem to play with to many cars to keep track of.

I like those wheels alot. I do think they will look big though, considering the spokes come all the way to the lip of the wheel.

Twin_Turbo

iTrader: (25)

Yes, unfortunately they don't have them in 19

blestx4

im interested in a pic when you decide. Polly Ta has 19's or 20's I believe but I know also it has ground effects. The turbo firebird with the username andrew91gt has pics early on with large c6 z06 wheels on it. Search 2000hp capable firebird. Probably seen them but with tubs and stance this car pulls the large wheels off the best I have seen on a firebird.

Andrew has 18s/19s of a C6 and they look to be on the ragged edge of what looks goo on a non gfx car....but some wheels work better than others

Best thig I can do is put my buddies 20s on mine and then get a pic of the wheel I want and photoshop it over them so I have the correct sizing from the 20s on there.... guess that's my plan.

Homer23

Those rims look good. Just get them and roll with it.

Mailman818

i was about to say to borrow your buddies. even like just the driver side and see how you like it.... i have the same body without the ground effects and i think it looks pretty good with a decent set of rims. ive put 18s on it tops but ive always wanted to put 20s to see how itll look. i think itll look badass.

Hmm, I was always under the impression that that car had 19's. Looks pretty good. I have been considering 20's lately as well (ZL1 wheels) but have been unsure if it'll look good or just donked out. That picture may have made up my mind. Although I agree, on a non-GFX car they may look a little too big.

That GTA looks good. I think I want 19s or 20s now. Will 19s/20s reduce handling?

What backspacing is your buddy using and how wide are those wheels? Do they decrease turning radius or rub? Obviously the car is lowered. But, does it sit at stock ride height with the bigger wheels? How much did he lower it?

Twin_Turbo

iTrader: (25)

lowered with eibach sportlines

the tires do rub full lock and the inner fenders need tweakign (the plastic) although the 92 has different inner fender platics than 90? and earlier.

MY1950COUPE

I have 20s on my camaro

Twin_Turbo

iTrader: (25)

yeah but you have gfx

goliath88

honestly, unless you lower it, its gonna look tall. go on youtube , you will see a few. i got 20's on mine but i got the Predator kit on my vert. so if you do it, kill the gap some. but to each their own, ima go 22's later on when im done with him.

Twin_Turbo

iTrader: (25)

What is a predator kit? already have lowering springs and intend to cut them down a little more

goliath88

body kit. id get the 20s before you cut anymore. dont wanna go too low. then youre gonna end up rubbing alot.

wgripp

iTrader: (1)

Nice stance for only using eibach sportlines!

So the tires only rub at full lock, its not bad otherwise? I wonder if there would be any negative impact during racing. What size tires is he running?

Was trimming the plastic on the inner fenders a big deal?

Any bottoming out of the wheels in the fenders?

How wide are the wheels? What's the backspacing on those rims?

Sorry for all the questions, I love that look!

rtimming was in 1 spot on the rear, I took out a section and fabbed a plate to go bhind it, it's sort of a bulged area.

wheels don't bottom out or other issues

these are the available sizes

20.00" x 10.00"+ 18, +34
20.00" x 8.50"+18, +20, +32

I think he has the et 18s, not sure if he has 10" in the back, will have to check
