18's OR 18's and 20's
 

I'm undecided on wheather I want to go with 18's all the way around my Firebird or do the 18,20 combo. Anyone have experience with either/or and what are the pros and cons? This car is not a daily driver.

Plenty of photos on the home page at the bottom where you can check out both combinations. Why did you leave 19/18 out?

Good call on both counts and just to confuse things a little more, 19s and 20s work well too and the 1" stagger is more contemporary unless you're going for more rake.

What year Firebird?

Here's 19s on the back of a 68 Camaro

and I think they fit just right. 69s and 2nd gens can handle a 20 better IMO.

As mentioned the first question is do you want 'rake'? Rake can be achieved through your suspension and/or rims. In the end its going to be a personal style choice and depend on your overall car attributes. I'm assuming you have a 'level' ride height, is it lowered or stock height? Do you like a little tire or do you like low profile. 17's with 50s can equate to a 19 with 40s (roughly). I find the best thing to do is have a person look through car examples (100s on this forum, pro-touring, team camaro) find a look and stance and then ask that owner/builder for the details. Sometimes even the rim choice itself will sway you one way or another once you see it on a car.

If Boze wouldn't have already dipped into my pocket we would be talking. Those wheels are the best new wheel I've seen for a while.:thumbsup:
The reason I went with the 19/18 combo is due to a stock front sub and 345mm on the rear. I wanted to stay with a 26 inch tall front tire which is the factory spec but keep the sidewalls the same size.255/40/18 With a 27.4 inch 19 in the back it works out that way. Now if you are running a 275ish 19 out back with around a 26" tire like was stock then I would probably run the 19 up front to keep the sidewalls close. Now if I would have went with a aftermarket sub and a 275mm I would have run the 19 as well.

Thanks Brother! I really appreciate it! And I agree with your tire/wheel sizing rationale 100%!

My car is a 69 model and I've considered the 18/19 combo but everything I'ved looked at in those sizes is way too expensive for my budget.

18s, 19s or 20s
 

As far as I know some manufacturers do not have 19s on all their models.
I like the Intro Titan's. not available in 19s. only 18s or 20s.
I like the Billet specialties Vintec, only in 18s or 20s.

I agree that the difference between 18s front and 20s rear is big. 18s front and 19s rear would be a lot better.

I think these are 18/20... Not 100% though... not a big fan either (may just be the rims)

These I like! ;)
