- JAJ replied to the thread Oil pressure dropping to critical levels under hard braking (Headscratcher).I looked at the oil pressure trace and RPM again with the thought of the Accusump in mind. Whatever is dropping the oil pressure has to run the Accusump out of oil in the process. If the Accusump is static-pressurized with 10PSI air, then at 90... (see full post)
- JAJ replied to the thread What am I doing wrong with my camber?.The current theory is that when he had narrower tires on narrower wheels with a different offset, he could tip the knuckle and tire assembly further in using the slotted holes in the strut. Tipping it in gave him more negative camber. Wider... (see full post)
- JAJ replied to the thread Oil pressure dropping to critical levels under hard braking (Headscratcher).Maybe an Accusump? It's only just a little bit more money. (see full post)
- JAJ replied to the thread Pirelli Trafeo RS tires.I just picked up a set of 305/30x19 Trofeo R's for this track season. I ran them a few years ago and liked them A LOT. They handle and they live through a lot more heat cycles than anything else I've driven. My experience is that they're the... (see full post)
- JAJ replied to the thread Oil pressure dropping to critical levels under hard braking (Headscratcher).I might be missing something obvious, but the oil pressure doesn't make any sense in respect of the RPM profile. Yes, it's low on braking and cornering in T1, but then as you bring the revs up onto the T2 straight, it's flat for a while and then... (see full post)
- JAJ replied to the thread What am I doing wrong with my camber?.My thought was that if you have to keep the top of the tire away from the strut to make room for the spring and its perch, the tire has to stand up straighter (less negative camber) than it would if the top of the tire could be angled in closer... (see full post)
- JAJ replied to the thread What am I doing wrong with my camber?.It does seem odd. Does the lower spring perch on the Ohlins kit sit above the top of the tire? If not, it could be part of the problem. (see full post)
- JAJ replied to the thread Play/movement at one wheel when parking brake applied?.Your bearing is fine. And the parking brake is more than adequate to take the torque of the wheel nuts. As I said, the GT350 parking brake is totally different than any other Mustang. It's a BMW-style drum brake located inside the rear brake... (see full post)

- JAJ replied to the thread Play/movement at one wheel when parking brake applied?.The parking brakes on GT350's are completely different than parking brakes on other Mustangs. Owners of other Mustangs will provide guidance that does not apply to your car. This thread is full of it.What you're seeing is normal on GT350's... (see full post)
- JAJ replied to the thread GT500 heat exchanger upgrade for mild track use?.I used to do track days in my 2014 GT500 and it came stock with enough driveline cooling to work without any problems. Didn't have a 20-second long straight, but otherwise, it was a track.My suggestion to you is to compare the driveline... (see full post)
- JAJ replied to the thread Stop Tech rotor.Well, that sucks. There might be one in someone's warehouse, but that's a tough slog. You do have options, though. I wasn't joking when I said run a left rotor on the right - unless you're running at 10/10ths, it'll work fine. Or, get another... (see full post)
- JAJ replied to the thread Stop Tech rotor.Try Dave Zeckhausen at Zeckhausen Racing. If anyone has one lying around, it'll be Dave.Or just find another left rotor and run it backwards. Unless you're running hard, nobody will ever know the difference. (see full post)
- JAJ replied to the thread Voodoo mods for reliability (autocross and some track).Calling @honeybadger...It's tempting to suggest that you do install the Predator oil pan, etc, but include a Predator 5.2 liter cross-plane crank while the bottom end is open. It'll work with your existing wiring harness and ECU and you won't... (see full post)
- JAJ replied to the thread Cup2R Tires Road Atlanta - Managing Pressure at HPDE Track Event.Get yourself a Motorcraft TPMS Reset Tool TPMS19. It allows you to retrain the BCM to recognize the (OEM) TPMS's you just installed on the car when you changed wheels. You start the relearn with a series of taps on the brakes and the start...

- JAJ replied to the thread Thoughts on how my Pagid 29’s are wearing.What I'm seeing is pads that have been run very hot. RSL29's are exceptional race pads so they can take it, but their condition is a result of going in deep and getting hard on the brakes late. Braking that way generates a huge amount of heat...
