Let me start by saying that I know there are other threads on this site that mention this subject, but I'd like some feedback from anyone who drives a BA XR8 (or any BA for that matter) and specifically those who take their car onto a race track (regular or otherwise).
A few weeks ago I had the pleasure of taking my XR8 to a no speed limit / open day at Wakefield Park. I REALLY enjoyed it but the standard brakes in my car let me down (and before you respond with "well why didn't you by the performance brake upgrade on purchase you damn fool?" the answer is that I bought the car second hand (10,000 Km), and that was not an option. Although, I must say knowing what I know now I would have insisted on an aftermarket upgrade, included in the price. But hey - retrospect is a beautiful thing !
So anyway, it was blatantly obvious that the brakes were not up to continued racetrack abuse (and in all fairness I knew that would be the case before starting and my strategy was to reduce the laps so's not to overheat them). I would do 3 to 4 laps per session and not only were the brakes fading but the rotors were warping with the heat. I would then go for a cool down drive and wait for the next session. The car went great and I can recommend heading to a race track for some laps to anyone. Even with mildly frustrating problems like this .
So I want to do the odd race day/hillclimb/ freakishly fast driving where appropriate and safe, and it's obvious I will need to replace my rotors, pads and fluid (I'd love to do the callipers also but no budget for that). After some enquiries DBA have two options for me regarding Rotors.
1. Upgrade to DBA4000 Rotors - Heat treated, will do the biz on the track, no question. $240 each
2. Upgrade to DBA std slotted rotors(Part No DBA504 S I think) - Not heat treated but far better than the standard brakes. $145 each.
DBA and the local Brake specialist reckon that I can get away with fronts only (I would do this initially, and eventually upgrade the rears as well.)
Has anyone given the standard DBA upgrade rotors a punishing on the track, and if so how did they fair ? Same for the DBA 4000's. Anyone out there got em' ?
I'd also like to hear what other mods people have done for weekend racing hillclimbs etc. I've got a fire extinguisher and am setting up a bonnet restraint for CAMS compliance.
Thanks in advance
