    Does your Dark Horse have the Handling Package? I’m guessing it does and you’re hearing the electric pump for the differential cooling system. (see full post)

    I’ve started doing more track days and I’ve noticed something consistent after sessions:After coming off track, I hear a continuous whirring/whining noise from the rear of the car. No vibration, no grinding, just a clean whine that goes away...

    I ran lockouts in 2021 - car lost a lot of low end power and torque - like 75hp. but the power band was super fun on the road course. Not super fast, tho.FWIW - I run the L&M Engine cams and we didn't see any issues with VCT under any... (see full post)
  • RII is a drag racing tire. I will be very polite and suggest you look at Bridgestones, Yokes, Falkens, Nankangs, Vitours, etc. they will all be faster and better than the Schittos, er, Nittos. Have a wonderful day.

    Wow - tons of great advice and information in here guys. Thank you! Absolutely no offense taken at all - if anything, I am very appreciative!Just some updates on my parts list: 1. Got DBA T3 4000 slotted front rotors - this was purely for...
  • Avoiding a quick "stab" at the brakes might help, rolling the pressure on just a little more gradually.
  • The rear spring choice is going to be a product of how you drive. The more you ask of the rear, the less spring rate you'll want. Tracks where you have a lot of traction corners may want a 700# rear. Tracks with a lot of long-duration, banked...

    Is anyone out there using Comp Cam phaser limiter or lockout blocks on their dual-duty street/track car? In the process of planning and doing a rebuild and just curious of everyone's direction. Comp stage 2 SPR likely going in. Thanks everyone.

  • I was annoyed with the stock slip n slide leather seats. So I bought a used set of 2012 Boss seats from a member here. Awesome. Not a true race seat but huge improvement and perfect for this in between-er type of car that I wanted to keep very... (see full post)

  • Along the way I got greedy with really sticky 305’s on track so eventually I picked up another set of LMR SVE wheels and built a little trailer to haul them along behind the car.I like that 305’s stack up as high as our S197s lol. Compared... (see full post)

  • The rear axle gradually got upgraded as things wore out. I was burning through axle seals so I installed the GT500 caliper brackets and rotors. Replaced the LCAs with maximum Motorsport parts, and eventually wound up removing the entire axle and... (see full post)

    No, the coils are binding on both sides.
  • I did a few events with just the new wheels and tires. I tried some good track pads on the stock GT brakes but that wasn’t nearly good enough. And the suspension was soooo soft. So I swapped in the usual Boss brembo setup together with what... (see full post)

  • You'll boil the fluid before you fade the DS2500. Keep an eye on wear. Measure the pads before and after running. If you see any negatives from high brake temp, it will be excess wear.Some cars can take those big friction numbers. Think about...
  • Yep, and they really fight rear locking. ABS can only do so much, especially since they all run the torsen, which screws you for braking. There just isn't enough diff lock to keep things happy.In general, any sort of front-engine GT-ish car...
  • I was just starting to get interested in track driving but the Mustang was always going to be a daily too and it got used as such. So any track mods had to be street friendly. (see full post)

  • It looks like they are running the S197 Ford Performance controller? I'm surprised that works on a S550. I wonder how many hoops they had to jump through for that?I have a controller off a GT500 CFTP. I don't know if the programming is any...
  • it was my first Mustang and my first rwd car with a stick and real power. It replaced my old Saab Viggen, which I also loved. So the Mustang was a big change for me, very different type of car obviously. (see full post)
