what is considered to be a "heavy wheel"? what is the amount oif weight on the stock rims we have? any help would be good, thanx.

Our stock wheels are 26lbs and are VERY VERY heavy. My SSR Competition rims at 14 lbs and 17X8 instead of the stock 17X7.

Do you have pics with those rims on your silver CL-S. I would love to see them. I will go do a search in the Gallery, but just let me know! Thanks.

I found the link

but the pics don't show up?!?!?! I would love to see them.

Type S,

I think a heavy wheel is a relative term. It depends on the kind of car you have and the amount of power your engine is making. For example, on our car, the weight of our rim is ~ 25 lbs; however, our 0-60 and 1/4 mile is quite respectable. Now put that on a Civic, Accord, or Prelude and I'm sure that your 0-60 and 1/4 mile time will be affected. So with that in mind, a 20 lb rim can be consider a relatively light rim for our car. Know what I mean?

Try to find something that is less than 20 lbs., racing hart cp035's are about 18 lbs. for the 18*7.5.

I agree with FDao that heavy is a relative term. Our stock rims are 24 lbs which is not too bad. The lighter you can get the better, but you can also be looking at a dramatic increase in cost. Not to mention if you get super lightweight rims that don't cost much you can pretty much guarantee that they'll get bent very easily. So cheaping out may not be a wise idea. In my opinion, when it comes to rims, I go for looks. Spending several thousand dollars for very high quality lightweight rims is not a very good value in terms of increased performance. You're probably not gonna get more than a tenth or two in the 1/4 mile with lighter rims especially since you're going with 18s.

Type S,

I also agree with GoldTypeS. Your 1/4 mile performance may not be that much better than a set of 17", even if it were lighter. This is because of rotational inertia as well as weight of the tires. SCC had an article about 2 months ago regarding weight of tires/rims. They compared 16"-18" tires/rims and found that although the 18" were lighter than the 16's and 17's, the 1/4 mile and lap time were slower...hmmmm.

GoldTypeS,

So, by going with those 18x7.5 (23.b lb) or let us say go 18x8.5 (25.2lb) Performance wont be negatively affected?

Thanks.

Nashua,

Going to 18" can negatively affect performance due to the rotational inertia, even though the weight of the rim may be the same as the 17". The affected performance will be in off the line acceleration, and arguably in apex acceleration.

Yea, FDao and EricL are the Physics gurus on the board...an asset to this community
I remembered the rotating inertia discussion a few months ago.

What material/construction should I look for that's gives you a good balance of lightness and strength for wheels? I would prefer light wheels, but I don't want to be buying new rims or fixing them all the time.

Stock, for now at least.

 

for strength/weight the best option would probably be SST (a form of forged): From:

http://home.earthlink.net/~cvlocas/

Forging (including SSF which is a true forging) results in a much stronger wheel. The wheel can therefore be made lighter than a cast wheel, while still maintaining superior strength. Multi-piece forged wheels have forged centers and spun rims. The rims are therefore not forged (designated as "forged/spun" in the table above).

Casting can be done in a number of ways. The most prevalent are gravity casting (pour the metal into a mold), vaccuum (counter-pressure) casting (suck the metal up into a mold) and low-pressure casting.

Relative wheel strengths are as follows: 1-piece forged, multi-piece forged, vaccuum cast, low-pressure cast, gravity cast. The strengths are only relative because weight (or actual mass) affects a wheel's strength, as does the actual design. Vaccuum (counter-pressure) casting is used almost exclusively by BBS for most of their wheels.

Thanks for the info empeters. Looking through that chart though, I noticed that most rims I'd look into getting are cast, not forged. Specifically, Fittipaldi's AV/Avus series. I also noticed that they're heavy as hell, but I really think they would look sweet on the CL and I'm mainly looking for appearance enhancements. Anyone have experience with Fittipaldi wheels? Are they relatively easy to scratch and/or bend as compared to other brands? I'm having a hard time finding any info on Fittipaldi rims regarding their construction and materials. Do you think the weights on that website are accurate? Also, does anyone have pics of these wheels on a 2001 CL? Or any ideas about wheels similar in style to the Avus/AVs.

me too I am having some tough time locating stats of those ADR Enigma.



I guess I have to go with 235/45/17 with 17x8.

Those Enigma are 17x8 but I do not know their weight? Anyone knows?

Also they are on the cheap side, some $165/each from http://www.rim1.com/

Thanks for any hints.

I seem to remember someone saying 24 pounds
for them. But I don't remember where.

So if I understand correctly;
-18" rims with the same weight as stock will hurt performance.
-18" rims that are lighter will be close to the performance of our stock rims.
-17" rims appear to be the largest size rim that will maintain overall performance.

Conclusion;
-Buy lighter 17" rims to increase performance.
