    ACR-X Brakes

    I have now done 5 events on these rings, and they had held up admirably - no issues at all. I've driven the car around the block a few times after the last day and I am happy to report that there is no shimmer/vibration at all that I can notice (Brembos would have been a little rough at this...

    My "ACR-X style" rotor experience: street and track

    I've tried these out on the track (as well as XR5 pads from the same manufacturer) last Saturday, and they work as advertised. It was a cooler, damp day, so I cannot speak to rotor performance in "maximum stress" conditions. The rotors looked as expected at the end of the first day with a couple...

    oh yes, same, if not worse, in the dry.

    ACR-X Brakes

    was re-watching some videos and found a clip from my very last day on Brembos, just before the picture showing damaged holes was taken. you can see how much the front end is shaking on the straight, and especially when braking into turn 1 - check out 1.45 and 3.40 in the video...

    ACR-X Brakes

    I re-used ST, DBA and Brembo fasteners on 2-piece rotors quite a few times (which is against manufacturers' recommendation). I have never had issues caused by that. I have seen StopTech fasteners loosen/back off at the track once, although I suspect improper assembly more than anything else...

    My "ACR-X style" rotor experience: street and track

    Nice find! Confirmed (now that I know where to look, they are almost invisible on mine at this point)

    ACR-X Brakes

    Initial bite is more gradual/"softer" with RB rings compared to Brembo. Either one has more pronounced bite compared to ST/D968 combination. As far as "why not just use ST": Constant torque is likely similar or higher. Maximum braking force/deceleration is, of course, unaffected, as that will...

    My "ACR-X style" rotor experience: street and track

    Unfortunately, Brembo Motorsports catalog only lists P/Ns for "assembley' ( which includes both hats and rings): 90.9303 and 90.9304. I do not believe the hats have any numbers on them, but I can double check tonight.

    My "ACR-X style" rotor experience: street and track

    I recently had a chance to try an alternative for Brembo’s “Wide Ring” ACR-X rotors, which provide larger friction surface, and accommodate “D1001” shape pad. As many of you know, Brembo caliper used as OEM on GenVI Vipers is able to fit both “D968” brake pad (SRT-10/ACR) as well as “D1001”...

    ACR-X Brakes

    Below is a picture showing pad wear for the "standard" EVO/CVS-V pad shape over RB ring. I did grind my next set of pads to remove material in that area and that helped with this issue. I put about a dozen of heat cycles on them on a track that's very ******* the brakes - I wore a brand new...

    Some pictures of my GTS at Pacific

    if your survived your first track day with a Viper at Pacific, in the rain, you will have no problems with this car! :2tu:

    ACR-X Brakes

    RB "Mustang" ring fits the brembo racing ACR-X hat. There a couple of spots where the pad ends up overlapping the friction surface of the rotor, creating non-standard wear. I do like the "feel" of initial application in high-speed braking sections, it is easier to modulate the initial...

    96 B/W in Bellevue/Redmond

    John at Cantrell Motorsports has done track preparation/maintenance on several Vipers in the area, including mine.

    Someone please make this for 2006-2010

    unless the roof/hatch/rear bumper are designed to work with it, the benefit to handling will be none or worse
