Wheel hubs for sure check them regularly for play especially rear left one. Differential flange is also a good idea to be checked for play from time to time. MT82 should be monitored for oil leaks as well. Monitor also Header bolts, Fuel Lines, Oil Lines, Radiator lines, Water Lines. Front Suspension: K-Member Bolts, Control Arm bolts, Steering rack bolts, Steering shaft bolts. Rear Suspension: Upper CA Bolts, Lower CA Bolts, Clocking IRS Bushings. Brakes: Calliper bolts, brake lines (in fact stainless steel brake lines are a must). Wheel lug nuts tighten to 150 ft-lbs between sessions this will extend life of the hubs especially important in the rear.OK, can we revisit this post for a minute.
Now I’ve done a dozen track days with this car. What parts & pieces should be getting more attention when inspecting for wear. I’m wondering if there are any parts on the s550 that I should pay Special attention to when tracking that I normally wouldn’t think about? As always, Thanks.
* Brembo at all 4 corners
What Brembos are you using in the rears?
I went with a 4 piston kit with 15" drilled rotors (which I have not been overly impressed with)
The GT350‘s with a proportioning valve. There are some guys on track that like to lock up and slide the rear to bring it around quicker. it’s great for that but I was just hoping to take some load off the fronts. To me though, it really didn’t feel much different than with the stock PP brakes.Which one? The GT350 OEM or Wilwoods?
Did you do any modifications to the master cylinder and/or brake bias? I would imagine a larger caliper in the back won't do much, especially without proper balancing of the bias and hydraulics.
The harder you brake (deceleration g's here), the less rear brake you'll want/need. Stronger deceleration = more load transfer off of the rear tires.The GT350‘s with a proportioning valve.
