IDK, 270mm is what they run on 220 lb dirt bikes, and stop them well. Using them to stop a 2000 (guesstimate) lb car? If they work out, that's a great price for more stopping power, IMO.I'm also thinking of trying out these oversized and vented rotors when put new pads in....so also looking for any available feedback on these as well.
My X3 is in the shop 3 hours away or I would measure. Anyone out there able to do this?isen't 270mm just about stock for the X3?
I just pulled up the PDF specs for my XRS I had forgotten I had saved...same stock measurements mentioned above.What is interesting is when you change brake kits on the streamline site the specs dont change. Tim
That is correct, I send them an email asking for clarification.What is interesting is when you change brake kits on the streamline site the specs dont change. Tim
Can you elaborate on why same size rotors would be dangerous? Thanks.For the rear going from 248mm to 270mm would be very effective and well worth the money.
For the ront, going from 262mm to 270, I'd pay 50 bucks, no more. The front should go to 285-290mm to have an balanced effect.
Going to 270mm front and rear would be dangerous.
The rears would lock up long before the fronts would effectivly slow down the car.Can you elaborate on why same size rotors would be dangerous? Thanks.
In the front the brake lever action increase would be 3%, in the rear it would be close to 9%^^My thoughts exactly but if someone does try it you could always add a bias control. I would like to hear how just a front conversion works. I question if there is enough change in diameter on the fronts to tell a difference.
