What about 18's?

I have noticed that 18's don't get mentioned much here. My friend has some 18's on his Talon and I think they are HOT. If the Talon didn't have a 5-lug pattern I would have threw them on my car for a couple of shows.

Anyway, using the tire calculator, It shows that an 18 with a 215/30/18 is the exact same size as our stock set up.

What are your opinions on this? I understand that the ride will deteriorate, but as little as I think it will it may be worth it to me. I ride in my friends Talon almost everyday and he is on 18's with some crapy knock off coilovers.

Well, 18's don't ever get brought up because we hit folks so hard for going with 17's.

Most of us are performance AND looks oriented, so we go for lighter weight rims, that look good.

Simple.


17's give a rough ride, imagine 18's. Ugh.

17's are way heavier than 16's, imagine 18's. Yuck.

Bloodlust, I got your PM and will answre it here.

It's easy man, while 17's may have less rotations at the tire, you run into a few simple problems.

Get a set of 17's, and the exact same rims but in 16's. the 16's will be lighter. For example, my rims in 17's weigh 15 LBS a piece. In 16's, they weigh 15.9 LBS. That's pretty light. However, the 16's only weigh 13.6 pounds. That's 2.3 pounds heavier, JUST FOR THE WHEEL. Now, times 2, that's 4.6 extra pounds the engine has to try to spin. Then times 2 more, thats 9.2 pounds total in rims I saved. You can do the same math for tires.

When we are trying to save a pound or 2 on pulleys, why not on wheels?

Next fact....

While yes, you can put thin ass tires on 17's or 18's and keep the same diameter as your 16's or stockies, you still run into the problem of weight, then RIDE QUALITY. With no sidewall to flex, you will damage your rims. With no sidewall to flex, you will bump all OVER the place.

Easiest way to do it? Borrow some rims.

When I switched from 16's to 17's, I could not tell the difference as far as a "rough" ride is concerned.

Default Re: 315cc injectors

if I was into show.. I would 18s JUST for the shows. They would look hot on the carpet.. but that is the only place I would use them...

NOW.. if you know somebody who can calibrate your speedo and you do not mind a slower take off... you can run 18s with more sidewall... but the whole assembly will be larger than stock and will really cut into your acceleration.. but will probably give you back on the top end.

Something else about heavy rims.. we are not talking static weight either.. this is ROTATIONAL weight.. the worst kind. Not only does the dead weight of it slow down the reaction of the suspension (wheels are considered unsprung weight) but in rotating all the weight you set up a gyroscopic effect that actually works against handling by making the wheel assembies fight against turning.

I gotcha thx a lot REDZ.

So in that pic that you have those are 16s?

I think i might keep the Mach 10s in 17" but in terms of tires i think im going to drop from 215/40x17 down to the 205/40x17. I understand the significance now in terms of weight. But ill be doing things others probably wont for even greater weight reduction ( taking my back seats out ) so if later on im still looking for more power when the projects almost finished i guess ill juz drop down to 16s laugh.gif

Thx again REDZ

if you're THAT concerned about 9lbs, just go on a diet :-D
that way when you're riding in it, your fat ass will weigh it down less smile.gif
lol, just messin bro, seriously though, 9lbs is really not that much..unless you can reduce like 35+ i don't think there is a difference.
