Default Un-Sprung weight experts!

I am seriously considering going from my steel 20" wheels, to a set of 19" TE37's. My biggest fear is that I will always feel that they look too small since I am used to seeing 20's on my car, but my question is, with the weight savings, how much and what kind of improvements could I expect?


Thank you!

Brandon

what's the weight difference. you'll prolly feel a little better acceleration. even though i'm not an expert, i don't think you will notice though.

you're probably gonna save like 15 - 20 lbs each wheel. My Te's in 19 weigh 19lbs up front and 20.5 rears. And if you think 19's are gonna look small, you're nuts. 20s are too big

19 inch TE37s always look perfect, but I was just saying that since my eyes are so used to seeing 20"s on my car, It might be a ***** to get used to. but damn, even if I save 10 lbs per wheel, 10lbs of unsprung weight each wheel is HUGE

it sorta depends what tire you mount...you can't run the wheels without them, and there can be vast weight differences

You have no idea what you are talking about. A 20" steel wheel is probably almost 50 lbs. Saving 25-30 lbs of unsprung weight PER corner will make a dramatic difference in the way the car accelerates, brakes and turns.

You won't be sorry making the change. I personally beleive 19's are too big for the car. 18" is where its at.

I don't think ANY of us can conjecture the change he "might" feel without first knowing the weight of his existing wheel and tire difference

Agreed. But generally speaking, changing from a 20" steel wheel to a 19" Forged aluminum wheel, with a commonly used street tire, will definately be a noticable gain.

19" LE37 (and TE37) with Michelin PS2s weight about 44 to 46lbs. Compare that to your 20" wheels/tires to give you an idea of how much you can drop.
