There are various aftermarket items that fit perfectly. Look at the Kurookie bumper & sides. I got the replica INGs that fits great & trunk spoiler people think is OEM.

Put it this way, my oem forged 19s made by Rays are lighter than your stern st-1s in 18". The 18" oem Z track 18s are DEFINATELY lighter than your wheels. Does that change your perception of oem a bit? Try buying the same forged quality 18/19 aftermarket. Your 18" sterns are 26-27lbs each. My 1" larger wheels are 20-21lbs each. The track 18" wheels are 18lbs each.

Plus you barely have any mods anyway.

OEM mods ftw can't go wrong with quality parts, I sell and fabricate mods that aren't OEM but I make the quality of the item my highest priority. Oem mods are great but aftermarket mods are better IMO depending on who and where it comes from, not to mention what type of part it is for the car.

This isn't a wheel thread or how many mods you have. Who cares!?

Btw, those arent all my mods on my sig. You talk but don't know what I got LOL

It all depends on the look your trying to achieve.


We cant all afford $2000-3000 rims, body kits, twin turbos, coilovers, etc.

some1 tell me what OEM means plz lol

Original Equipment Manufacture.

Nice attitude. Just trying to give you ONE example why people like OEM vs aftermarket. I just used your wheels.

Sorry, I don't really care enough to know what mods you have other than the sig. If you don't like oem that's fine. I don't care. It's not like I need to justify my modifications to you.

In this case, while overall weight always matters, the larger diameter still equates to a loss in acceleration, braking, and turning radius...

How can the larger dia hurt performance when the overall weight is lighter than the wheel in question? While WHERE the weight is makes a difference, you cannot make that distinction w/o intimate knowledge of each wheel in question. Which I know you don't have. So w/o that knowledge, overall weight is what is important.

And how is a larger wheel going to hurt the turning radius when the over all diameter of the wheel/tire is what is important?

my Volk 19"s are lighter than the OEM 17" I had... 1/4 mile didn’t suffer (neither did "felt" acceleration).

I will say however, the PIG HEAVY Akebono OEM rotors DEFINITERLY affected acceleration!

So anyway - I'd take bigger lighter wheels over heavier smaller wheels any day.

It's the circumference that matters more when we're talking about rotating mass and unsprung weight... we can leave the rubber out of this, it's not going to matter much until we get to traction, and either way, you're going to be adding more weight anyways. Either way you put it, a smaller, heavier wheel will put more power to the ground and will be easier to break loose than a lighter larger wheel...

I know, it really isn't that big of a physical difference until you jump 2 sizes...

Take it up into the mountains and you'll see a mix of good and bad.

Diameter doesn't have to be larger; you have a larger diameter wheel, but low-prof tires and so the overall diameter may end up being the same or slightly larger/smaller. In fact, changing from my 215/55-17s to 255/35-19 rear and 245/35-19 front will change my diameters from 26.31 inches to 26.02 and 25.75 respectively.

I'll go with the lighter wheels thanks. A lighter wheel is always better in the context we are discussing. But if you have an article that explains your theory, I'll browse it.

Dia doesn't come into play until you put a tire onto it.
