: 16 vs 17 inch rims

As far as drag racing goes, would 17inch rims and tires (17x8) cause slower 1/4 mile times vs, same brand/tire 16X8?
Due to inreased rotating mass among other reasons?

Even if so, overall and in regular driving are 17's worth the extra money over 16's?

Thanks

Most of the problems with lower profile tires is the wall needs to be much stiffer. Stiffer walls mean less traction basically. 17s on a FWD is real bad idea, on an AWD you can get away with it if you run good quality rubber at least until you're putting down serious power and then you'll have issues too. :( Don't get me wrong, I like the looks of 17s vs. 16s but if looks made you faster then Hondas might actually be worth driving.

I went from the stock 16s with Goodyear rubber to 17s with Nitto 450 rubbers and my 60' improved by about .3. I think the only bad thing about going up in size is the added weight, that is why I want to TE-37s :).

Yep, I bought my 17's purely for looks AND the fact that the lower and stiffer sidewalls make for great cornering and handling.
17x7 Excel Snipers (42 offset) w/225-45-zr17 Pirelli P7000 Supersports. Would highly recommend! Have yet to see tires hydroplane in pouring mountain rain at 70+. Maybe not for drag racing though for reasons mentioned above.
Oh yeah, the rims weigh less than the stock ones too.

All other things being equal...a 17" wheel/tire combo is going to produce slower 60' times and thus slower ET's than a 16" wheel/tire combo on these cars. That is a fact.

Are 17's better for handling? Yes and no. The lower profile tire can help, but the extra unsprung weight and rotating mass hurt you more. Do you see hardcore autocrossers running on 18" wheels with ultra-low profile tires? No way. They run on smaller wheels.

Yeah, I think the decision to go up in tire and rim size is for really only for cosmetic reasons. :cool:

And the Moda wheels I choose are much more attractive. Why not by new 17's and buy MY 16's with retreads for the strip :) :)

While I agree with the autocross argument Shawn95Tsi stated, and I already stated my reason for my 17" rims, etc.
Could somebody answer me this: If the 17" rims and tires weigh less than the stock 16's w/205-55-16 on them AND the diameter of the 17's w/225-45-17 is roughly the same as stock AND with approx. 20mm more available traction: HOW could this produce WORSE 60' and 1/4 times?!?
I'm just curious...not argumentative. Cuz' I love my rims and tires. But would not put them on specifically for dragracing.

I said all other things being equal. Meaning, same car, same model of wheels, tires, etc. Yes, if you go from a heavy 16" wheel on a narrow tire to a lighter 17" wheel on a wide tire, your 60 ft times are likely to improve.

What 17" wheel did you buy? If you had gone with the 16" version of the same wheel, your wheel/tire combo would be lighter overall, and the rotating mass would be concentrated more closely towards the center.

True, but you can't fit big brakes under 16" wheels. Braking on our cars is very suspect if you are on the track for any real amount of time. Auto-X is probably O.K. since the runs are short with lots of cooling time in between.

17" wheels would be appropriate for a road racing situation. Although, there are 16" wheels designed with racing in mind that provide clearance for larger brakes.

I should have been more specific, you can't fit the AEM big brake kit under 16" wheels. I want those brakes bad!!!!

Me too! I was checking out a pair on a friends 97 gsx and they are damn nice. He has the ones with the blue hats and they look sharp as hell! He is an avid autocrosser and loves them.

I bought 17" specifically for less sidewall and better **high-speed** highway handling and cornering. Not to mention the 7" width so I could put a little more stability and traction at the corners. The stockers were dented up and I really like the seven spoke design I got. Plus, I also want to put on the AEM big brakes upgrade, too!

I bought my 17" rims just to fit over AEM brakes. I've already ordered the brakes front and rear. I've also already got my stainless steel brake lines and caliper lacquer paint.

I can't wait for the brakes to arrive!

Ohmygawd, what did you pay for the front and rear kit, if you don't mind me asking? Did you get new calipers (not sure they are even available yet) or just the stock relocation kit? You will have to post some pics when the project is done!!
