Man those Rotoras are SICK!!! Real improvement, IMO. Enjoy them safely! I'd be looking to do the same sometime soon.

Anyone have an idea of how much these compare to stock in weight?

do your brakes still squeak with the new rotors?

WOW!!! how are they holding up? I get paid this week!:D

:o

They are holding up great! I have noticed increased brake dust in the front but I had lots before to. I think they really give the car a hot look and would reccommend them to anyone. Vivid was great to deal with also. No brake squel or squeak. I am planning on getting the Volk SF challenge rims which will really complement the rotors! I will post pics. when i have them installed.

Now that will look great!

Yea me too. Volk SF-C all the way;). And yea thanks for the up date. Now I just have to order my set :D.

Correct me if I'm wrong but I think the Volks are very light rims, right? I love light rims...
Where are the pics?:)

I ordered 19x8.5 SF Challenge , They should be here by friday, should have pics. by next tuesday. They weigh 22lbs ea. The tires i got are Toyo T1-S Proxies, (245-35-19) Those weigh 23.8lbs ea. The total should be about 1.1lb lighter each than stock.

People say that stock rims are 21.5lb so I reckon that the proxies are much lighter than the potenzas, right?
You'll have the same setup on all 4 corners?

Yes, The potenza's are 25.9 lbs. And yes, i will have the same setup front and back. This will allow me to rotate at least front to back, as the proxies are directional, side to side is not an option. I dont feel there is a real need to increase the width of the rear tires, wheel spin is not a problem and it takes away some handling IMO.

thanks for the info!
what about 225/40/19 front and 245/35/19 rear? this way the wheels are almost the same size in diameter with stock, they differ only a few milimetres. I've done tha calculation on this site:

speedo doesn't get messed up... very small difference. I'm saying this 'cause I think 245 is way too thick for a front tire, in my opinion...

Well, the rims are in but the tires are not available. So i just ordered Perreli pzeros neros.
They should be here by friday and hopefully pics. by next tues. Perrelli's are only 23.0lbs and are rated pretty good. Time will tell!

Let me Know what you think!

Looks Good
Now you just have to fix the gap in the wheel well.:D

It looks really mean:) nice job
