Looking through the new Grassroots Motorsports TireRack has this wheel listed as coming in an 18x8 and weighing in at 14.5-15.2 lbs.......I checked with TireRack and the 18X8 only comes in 5x108 and has a 47mm offset. What do you think the chances of getting SSR to offer this wheel in a 5x114 bolt pattern are? I would definately be interested if for no other reason then to say I have lighter wheels then ULLLOSE.....

Not going to happen... Tirerack has the 18X8 48mm for the RX8 at 17.5 lbs for $469. All SSR comps 17"+ are now 2 piece wheels that is why they gained a pound.

As slow as you were in my car do you really think you need new wheels.

Are you saying that this paticular 18x8 SSR Type C-RS in a 5x108 and 47MM offset weighs more then 14.5-15.2 lbs?

I am saying they already have the SSR comp for our car and it is 17.5 lbs. That may have to do with offset, hub center and spoke thickness. The lightweight version may have a thinner spoke for lighter cars. Also I am sure the print add weights may not have been updated to reflect the new higher wheel weights, might be bad for business to ask people to pay the same price for a wheel that has gained weight.

This wheel is supposed to be "new" according to the add in GRM. Yeah, it might not make sense to sell a lighter wheel for the same price but if we get enough interest they might be willing to compromise.

Interested Jason?

I stopped spending money on this car a long time ago... No way I would spend another $2k to drop 1 lb per wheel when I can drop way more than that for free.

Midpack Mike tried to get a wheel deal together a while back and could not get enough people.

I know over on the Solstice forum they had a deal going for Volks from one of the guys at Tirerack, sounds like 5 sets can get a custom order from them:

When I tried to get the group buy together, it was for 16-17 lbs. Kodiaks. Cost was going to be right at $2000/set IIRC. There were three very interested potential buyers from this board, but we all had concerns with delivery times, order fulfillment and the general "hassle factor" rumored to be common when working with Kodiak. The Solstice group was a bunch of panty waists, complaining about cost and "resale value" or some other nonsense, so they weren't in...now, they are talking about spending nearly twice as much on Volks

I also contacted CCW, Jongbloed and a few others. Interestingly, not only were the costs higher than Daryl at Kodiak quoted, but so were the weights. I believe it was Jongbloed that was thinking somewhere around 17.5lbs. was about as low as they'd get the rims, given their strength requirements. I've presently settled on the OZ's at 18.4 lbs and $300/each. If someone can come up with a more attractive option at +/- $2000/set, I would consider selling my OZ's and buying another set.

BTW, after my strong second at Atwater, shouldn't that be "First Loser Mike", rather than "Midpack Mike"?

I'm going to make a couple calls on these wheels and try to get the true story. Looking around the web I'm not the sure the posted 14.5-15.2 lbs per wheel is 100% accurate. The RS is supposed to have a cold forged lip but other then that it looks comparable to other comps.

Seeing that the wheel size and offset is already being produced I think getting the correct bolt pattern should not be too difficult of a request. If I can get a few other folks on board and the weights are lower then the normal comps it might be worth it. Of course, all my wife knows is that I just bought an extra set of wheels for the RX8 and she could really care less how much they weigh....

I think what you were looking at was the SSR Comp-H which is a two piece welded hybrid wheel. They wiegh in around 17.5 lbs and currently cost 469.00 each. They are also discontinued and we are limited to the wheels we have in stock. SSR is still trying to recover from the buy out that happened 1-2 years ago by Tanabe performance.

The SSR Type C-RS to my knowledge is not made to fit the RX8.

However for reference the SSR Type C-RS is built in an 18X8 55mm for the Solstice and it weighs 18.4 lbs.

mwood

As does the OZ Ultraleggera (weighs 18.4lbs)...for about $650 less a set...

The option that is still worth exploring, imho, is getting Kodiak to build another 5 sets (at least) of the wheels he did for baggy. Should be sub 17lbs. and sub $2000/set.

Cooper47

What's interesting is that in Jasons' article in the latest Sports Car most of the Top Guns don't give a whole lot of credit to light wheels. Yeah, if you got the money you should get them but it sounds like the time difference is almost negligable in most situations.....

BTW - Interesting post about the Solstice wheel weight. I have a hard time believing an 18x8 can go from 14.2 to over 18lbs with just a change in offset. Must be a mistake in the TireRack ad.

Keeping in mind this is just the results from one driver on one car. In Jeff's case the C4 can drop 5 lbs per corner (24.5lbs VS 19.5lbs) and he only found that to be worth .2, but he also added that is well within the normal range you would see from run to run with no changes as no one is constant enough to make the same exact run every time. He also uses a high end data system so I know he did not just pull this out of his @ss.

A car with a lot less TQ than a C4, mine put 322 tq to the wheels, and weighs less than the 3200 lbs or so a C4 weighs could see more gain. If you were able to take 5 lbs per corner off a Miata you might see more of a gain. I think the RX8 is someplace in the middle.

Funny how people worry so much about wheel weight when we put on heavy tires. If weight was the most important thing we would all be on 245 A6s and not the V710 or 285 Hoosier.

lol, does your hamburger look like the picture on the menu?

I'm currently on the South Beach Diet so my hamburgers don't look like anything on the menu. What about these wheels? I think they are now making them in a 18x8....

Every tenth of a second counts. Introducing TRAKLITE - our latest high performance wheel. Because it’s a one-piece forged wheel, TRAKLITE wheels are stronger and lighter than cast wheels. They immediately improve handling, braking distance and, most importantly, acceleration. Less un-sprung weight helps you get off the line quicker, so you can stop spinning your wheels and start racing them. The TRAKLITE is available in glossy black and silver in 15” and 17” sizes.
