Sports Design Wheel Weights *Updated with Pictures!

For those who are curious on how much the Sports Design Wheels weigh, Front 18X8 25.4LBS Rear 18X10 29.2LBS I had the center pieces painted black so before I mounted the tires, I was able to weigh them. I just used our home weighing scale so accuracy I'm guessing is +/- 0.2 lbs

I wanted to know that ..thanks!

Good to know, thanks for the post. I weighed mine with the tires on since I wanted to learn how much more weight I was carrying over my lighweights on track. All I can say is that those darn sport designs are NOT light!

Boy these wheels are heavy! at least compared to some of the aftermarket ones like BBS RS-GTs which are only 22 lbs. But I know they'll take all the bumps, potholes, high speed turns and rumble strips .etc as they are the first GT3 wheels which were battle hardened in Nurburgring by Walter Rohrl Here's a pix of the wheels after I got the center pieces painted black. I'm really happy I've always love the looks of black wheels!

What did they run ($) to get painted? I will be back in the area in 5-6 months and want to paint my SD's as well.

$85 each center piece. $25 each rim lip for the clear coat. I seperated the center pieces from the rims myself, with that damn special tool.. "triple square" bit/ 12 point torx, luckily carried at Pep Boys and brought the center pieces to a local paintshop here in Virginia Beach. I initialy wanted to do powder coating but I am nervous about the heating process so I just opted for painting. I just made sure that I asked for the paint shop's darkest black and toughest/top quality clearcoat. I also had the same clear coat applied on the lips after I striped the faded/scratched old clear. I then polished them(that needed a lot of elbow grease). Removed the scratches from the rim lips by sanding the spots with 600 grit paper, and polished the rests starting with 1500 grit and finishing with 2000 grit with plolishing compound to wet the sand paper instead of water. Too much work but rewarding if you're patient. Which is not me

RSGT's are only 20 lbs in size 18. I think the rears are 21 lbs at the most

How in the world did you get the bolts back to factory torque spec??????? Everybody I have talked to (including Wheel Enhancement) said they will NOT remove the two pieces and instead mask, etc., since breaking the seal and the bolts are damn near impossible to get back original.

I really like them. I'm not just sure 'cause a couple of listers said that they're using spacers with them. They'll be my 2nd set of shoes If you want to be exact: Source: http://www.bbs-usa.com go to application guide section Part / Finish Size ET Wt. (lbs) RS928 - DBPK 18 x 10 65 22.10 RS928 - DSPK 18 x 10 65 22.10 RS925 - DBPK 18 x 8 50 20.6 RS925 - DSPK 18 x 8 50 20.6 RS927 - DBPK 18 x 8.5 56 21.0 RS927 - DSPK 18 x 8.5 56 21.0

Final torque of 145 inlbs. cross torqued first to half(75 in lbs). Don't ask names, but Its from a friend in engineering section, BBS. You know how those liability lawyers are Make sure you have the right "triple square" bits too. You dont want to strip them when you first remove them. Replacement will be a challenge to find but possible.

LVDell, Also, if you gonna do this, ensure that the mating surfaces do not get painted. Very close tolerance.

Car's looking sharp Mike. I love the sport design look, was going to buy a set but bailed out for the kinesis. Im planning to get my kinesis centers painted black in Spring, you know of any local shops? I was thinking about sending them to Eric at Bumperplug to do the job when Im ready.

Thanks Vove! Smart choice on Kinesis. Much, much lighter! Imagine the extra 8 lbs this wheels has when they start spinning. I used to balance helicopter rotor blades, and a 5 ounce balancing washer equates to more than 6 lbs of weight when spinning at almost a couple of hundreds rpm. The shop I used is just a regular auto body paint shop. Very knowledgeable though. I'm not sure if you want to travel that far from DC, but they're down here in Virginia Beach. I'm sure you'll find good ones up there.

Mike, the black wheels look great! They remind me of my old wheels which were black, very aggressive look! Have you thought about polishing the lip? It will make the black centers pop out a little more. Also, pretty interesting about the weights of the rims. My LM's came in at 22lbs and 24 lbs and they are 19s.

Jon, Thanks! I love the agressive looks of the black centers. I did polish the lips. Used 1500 then 2000 grit. Kept the sand paper wet with the polishing compound instead of water. Then finished them off with just the polishing compound and lots of elbow grease. I still had the lips coated afterwards with that tough clear coat 'cause that iron particle from the brake pads left on aluminum surface of the lips for a week, coupled with moisture will rapidly create pits of corrosion due to the dissimilar metals.

The black wheels look fantastic with the speed yellow.

Mike, those wheels look great black in combination with the polished lip and yellow 996. I recently acquired a 99 Iris Blue tip/cab with the same 18" Sport Design wheels. My intent is to have the centres painted in Shadow Chrome. Thoughts/Comments? Also see you have painted your caps black, did you have the logos masked when applying the black or are they new logos prior to clear applied.

Hey Mike, Was that after having seen mine? Ciao, Johannes E. GT3CS

Thanks for the kind words. I'm really happy with the results on mine. I'm not sure what shade is shadow chrome exactly is, but if its almost the same as the orig color but a little darker, I think it will look good on iris blue. On the caps, yes, they masked the logos and painted around them. The wheel centers, I removed them myself cause I want to make sure it get done right. They will need the "triple Square" bit(12 point torx) that you can buy at Pep Boys. They're real tight when you remove them, cause they've been there for a while and they a a little bit of thread lock. Just be careful and dont' use power tool to break the torx(to prevent striping). The torque when you put them back is 145 IN LBS. Thats INCH lbs. If you seperate them, make sure they don't paint the mating surfaces. Realy close tolerance. I would make sure that they bead blast the old paint to havethe new paint something to grab on. NOT totaly remove the old paint. Rough blast for the new paint to grab on. Good luck. Hope that helps. **Just a disclaimer, This is a DIY**

Johannes, I might have seen your's but Im not sure I remember... happens a lot after 40 I've always love the black Fuschs on the 930 and other old 911s. I really like that serious mean look when the wheels are black.

AGREE 110%!!

Dell, My post # 21 above hopefully will help more for you if you're planning to paint your SDs. I'll be glad to help if you ahve other questions.

From Wheel Enhancement. Although this is a boxster, it's lapis blue...I'm not sure how close this is to shadow chrome.

Ok, so I know this is a CRAZY old thread - but I wanted to say thanks to Carrera Mike for giving me the confidence to undertake this project. About a month ago, I found a set of Sport design wheels in a field! Yes, no joke - in a field. They were in a crazy shape of disrepair and neglect (no surprise right - they were left in a field!). I researched the process, bought a couple of tools and supplies - and I jumped in! First I broke the wheels apart - I used the correct bit to back out all 80 bolts, and got a big rubber mallet to break them apart. From there, the sanding began. I stripped off all of the old paint and the clear coat - quite a tedious process! Hand cleaned and polished each of the 80 titanium screws! Sand, sand, sand some more! I got the lip to a pretty high polish where I could live with it - not perfect for sure, but it looks great to me. This is not a concourse car! I bought paint to be sprayed through my compressor air gun... First I layed down a coat of primer, then the paint, then the clear coat. I painted the face and barrels to match my car. My car is a Meridian Metallic Silver. I bought new center caps and painted them as well. All in all - I am really happy with the finished product. I will be mounting them next week and will follow up with mounted photos if anyone cares...but just thought I'd share my experience. Let me know if anyone needs any help or has any questions. I learned a couple of things as I went along and I happy to help if anyone needs it! Cheers, KJ
