Default 19" Wheels to small for ISF?

I noticed someone was selling 19" Vossen CV1 Concave wheels 19x10 et38, 235/35/19 tires on them. Just thinking if 19" wheels would be too small for ISF, any opinions?

More like your tires are too small for the wheels.

ISx50 cars run OEM 18's on the same body size. 19" is the proper size but 20" does look good as well (but much less sidewall is needed to run them)

Its all about personal taste, and the specific wheel but i think 20s look a little bit too big on Isf. 19s look great..

Dang im late to post, but stock BBS are 19's. There's a thread for those running 18's (most of the ISx50 guys run) which I think is too small. But its all up to you and the route you choose, smaller wheel with more rubber or more wheel with rubber bands for tires. Happy modding bro!

I agree, although it depends on tires/offset/fitment fo shizzle...18's can look stellar on a dropped F with the right tires...stock height 19's look beautiful...I have 20's that fit quite well as far as how the ride height looks, and they are pretty flush with the width of the fenders (not my efforts....they were on the F when I bought it)

It's all personal taste. I've seen some run 18s for track purposes, 19s for everyday street driving, and 20s for shows. There will be those who argue that 20s serve no purpose on an F mainly because it would degrade its performance capabilities, but it comes down to one's personal choice. 20s IMO look great on the F, but I personally don't feel the need for larger wheels.

I remember the day's when 15" alloys were a big deal.

Would those wheels rub? Is the offset correct?

i have had 20s and went back to 19s for a better performance tire selection. 20s look amazing, i dont think anyone has squeezed 21s

Talking 19 inch wheels might be it

I too remember when 15 inch wheels were ideal according to the knowledgable. Then 16's started creeping into the picture. Soon there were plenty of choices, but some started wondering. What was the ideal size from a performance standpoint.

I read an article in a performance publication that said that anything over 19 inches was a waste. A wheel manufacturer based that decision on physics. I accepted their thoughts and calculations but have lost the publication.

I'm pretty sure that for maximum performance, keeping unsprung weight to a minimum is what we'd aim for. Accept that 19 inches is ideal and then find the lightest and strongest wheel for that weight and size (including width). Change tire sizes to gain or reduce overall diameter and width.

By the way, the strongest and best wheels are made of steel.

When Toyota put 19 inch wheels on these cars, I think they did it for a reason. There is not much on an F that isn't there for a reason. That is why I bought it.

I know the factory ones are 19" I just didn't know if going to an aftermarket one the 19's would look to small on the car but looking at it more and more 19" is probably the perfect size for ride wise and for performance.

I had 16s on my 1987 Supra turbo five star rims. I thought it was the coolest. 20s look great but not enough sidewall for me.

Something to keep in mind - mechanical and visual performance may be completely at odds. At the end of the day, the owner decides what works best. Many of the wheels I see installed on this forum are not at all intended to improve mechanical performance, but are intended to align with bosozoku or VIP visual ques. Saying this configuration does not perform is ignoring the goal - owners looking for "stance" are working to achieve visual performance without regard for mechanical performance. So, saying 19" wheels are the "best" from a physics perspective means nothing to this crowd. It's not in their requirements at all.

I don't disagree with your statement, but I do believe some clarification is necessary.

Oh, yeah, I'm a mechanical performance guy too...
