Not really that interesting but just for shi_ts and giggles I weighed my new setup and decided to share the info. Not sure what the stock chromies with tires weigh but maybe someone could chime in and let me know.

Fronts 19x8.5 Toyo T1r's 275 30 19: 43 lbs.
Rears 19x10 Toyo T1R's 245 35 19: 45 lbs.

I also wieghed my rear dr's (MT's 265 40 18's) and Kosie's 18 x 9.

Rear drag setup: 44 lbs.

What are the stock wheel weights?

squidj

DAMN, I just looked at your wheels. They are awesome.

jangy

Stocks with tires are 50 - 60lbs depending on tires.

bassn_07

Yeah...that sound about right. I was thinking that I saved about 15 lbs per wheel which includes the Evosport rotors.

jangy

That is conservative. You likely gained 8ish on each wheel. Would have been ten but I assume you went bigger and wider. You also gain about 10lbs per corner with the EVO rotors. I can tell a major difference in just the HREs vs OEM. Do that and the EVO rotors at once and I bet you notice a big difference.

squidj

Thanks, that's great weight savings with awesome wheels. Talk about a WIN WIN.

jangy

HRE competition series are one of the best out there. The best win is that we are talking about unsprung weight... Big difference in acceleration.

aganzon

I felt the difference in performance when I installed my C97s. I can even tell mid-speed accelleration is much better. I don't even have to step on the "go" pedal as hard to get to the speed I want to be in. I don't know if I make any sense in trying to describe it...

In addition to the reduced unsprung weight, the reduction in the rotational inertia is another factor to the more responsive feel in accelleration. I'm planning to put Evo rotors once the OEMs need replacing. Evo claims >8 lbs of weight reduction on each corner.

9 lbs reduced with the HRE C97 + another 8 or so lbs for the Evo rotors...that's over 17 lbs per corner and over 68 lbs of unspung weight taken off of the suspension. Can't go wrong with that! While our cars may not have to sure-footedness of a running back, perhaps these reduction in weight and rotational inertia might bring it's handling closer to a linebacker.

Kidding aside...the comp series is a great choice.

zoink

So I'd guess the weight is about the same as BBS?

jangy

Yes they are. BBS is a damn good wheel.

juicee63

my stocks are 66 lbs rear 64 front thats the 2 piece amg rim.

same size

bassn_07

Same size as my stock or HRE's rims?

The HRE Comps weigh less than BBS LM's.

I got my first set of Comps (C21's) back in 2005 and they weighed:

Front 19x8.5: 20.50lbs
Rear 20x10: 20.50lbs

Yes both front and rear were the same. Verified at Evosport.

My BBS LM's on my M3 weighed about 23lbs each 19x8.5 and 19x10. I wont comment on quality though. I got a chance to look at my BBS LM's real close before I mounted another set on the GT-R--- rear step lip as well for add strength!!!

I do think there are other BBS Wheels that weigh less than the LM's...

bassn_07

Did you ever have any problems with your C21's? When you say "I wont comment on quality though" I'm trying to figure out if it's HRE or BBS you had quality issues with. Please let us know.

blackbenzz

Wow that is light!!!! Can they be used on a race track (road course) without falling apart?
BBS RSGT is lighter than LM's. RGR's are lighter too I think

Vic55

Im sorry that might have come across as a bad rap on HRE which is not the case- I have owned 6 sets of their wheels and have them on 2 of my 4 cars now.

My only issue with HRE ever was with the C21's, the paint started chipping from hour 3 (yes it started peeling around the logo when I got home). Evosport took them back and mitigated for me with HRE- HRE fixed them and all was well until I sold the car. Props to Evo and HRE for handling the issue. It just was odd that the paint came off so early in the game. I was one of the first ones to get the wheel.

jangy

That is why HRE wheels are now powdercoated.

I have tracked mine and am EXTREMELY tough on them. Never a break.

Vic55

Well my other 5 sets were not powdercoated and never had issues... I think it was when they were using an outside vendor for paint.

juicee63

My stocks are same size as your new wheels. And unfortunately nearly 100 lbs extra rotational weight.

Your 1/4 mile times should really improve with the new rims. Lets get to the track buddy

bassn_07

Vadim is bringing my car to me tomorrow and we're supposed to hit Sacramento together but the weathers not looking very good right now . I'll still hope for the best. DA was looking really good...negative numbers.

BenzoBoi

GL buddy! Keep me posted on how you do!

bassn_07

Rain looks to be in the forecast but you never know. More than likey it won't happen . Thanks anyways.

bassn_07

Say when!

zdkdeeier493

Could you pls post some pics of your C20's on the car?
