  1. 17 GTPP, smaller pedal extension?

    There are a few options. They are all 1.5" that I've seen, and made for rubber pedal pads, not PP pedals. It would be easier to make my own than mod one to be shorter, I think.
  2. 17 GTPP, smaller pedal extension?

    I'd like the clutch pedal about 0.5"-0.75" closer to me when it is on the floor. I'll live with it being 0.5" closer at the top of travel, but not 1.5" like the extenders I'm finding. Anything out there for a solution for me?
  3. Thinking of going from a GTPPP to a GT350, not SRSBSNS but will autocross - input?

    I looked up the relative PAX change. Looks like the pax is predicting the GT350 is only 0.54s/min quicker than the previous top car in FS, presuming it becomes the new car to have for the class. So I guess some combination of the GT in FS sucked so bad before that it didn't get that much...
  4. Thinking of going from a GTPPP to a GT350, not SRSBSNS but will autocross - input?

    Ok, back after personal life disaster. What classes did the Gt and GT350 end up in?
  5. Thinking of going from a GTPPP to a GT350, not SRSBSNS but will autocross - input?

    Wait, what? How likely to end up in FS next year are we talking?
  6. Thinking of going from a GTPPP to a GT350, not SRSBSNS but will autocross - input?

    Anybody compare them? I'm comfortable with the level of pax competitiveness in street class from the GT. Wondering about the GT350. Several people have said I won't be able to get -2.0 front camber out of a street class 2016-2017 GT350. I have this vision of the GT350 being the same car, but...
  7. Autocross: Outside front edge tire wear

    Stock ford performance package dampers. Zero static toe rear. A hair of static toe in in the front. Rear tire pressure 34-36 psi (this gives even wear and seems pretty close to right for grip). Front toe bushing compliance on this car is so sloppy, who knows what the dynamic toe is doing at...
  8. Autocross: Outside front edge tire wear

    A mix of surfaces and drivers. Drivers have been me, a codriver who drives roughly like me, and a come at it from the bottom codriver. 48 runs (~80 second runs) on a mix of a single corner on space shuttle braking zone runway concrete (very rough on tires), a little regular runway concrete...
  9. Autocross: Outside front edge tire wear

    Here is the wear I've been getting with the jacked up pressures. Is the carcass of the RT660 curved so there is more tread ply under that edge, or are these a few runs from trash like the previous tires when they got to this point?
  10. Autocross: Outside front edge tire wear

    I've given that advice. Doesn't apply here :) In low speed elements I can use a little throttle to slightly reduce required steering input, but everywhere else, it is edge of understeer. Since I drive the car to the edge of understeer as much of the time as I can, more front wear than rear is...
  11. Autocross: Outside front edge tire wear

    275's on 9" wheels on the front of a 17 gtppp in FS. -2.0 camber. Every tire I've run on the front of this car (5 autocross sets in 2.5 years) has corded the outside edge well before the center of the tread. The last set was GY SC3 run at 38 psi. Outside corded with 5/32 left in the middle 5"...
  12. Budget 18" wheels for F Street on a 2017 PP1 GT

    So the listing for the OE FR19c 18x9 says it doesn't fit over special package brakes, but there are mentions on this forum of it fitting. Anyone here actually mount them up and find they didn't fit,r or them on a PP1 car?
  13. Advancetrac issue

    There is a spot on our local airfield venue that regularly causes the stability control to turn back on. It is an undulation in the concrete, that, if it happens to be mid sweeper in 3rd gear, causes the rear of the car to hop sideways 6" or so (it doesn't leave the ground or anything, just...
  14. Budget 18" wheels for F Street on a 2017 PP1 GT

    Actually, for our local courses, I think smaller diameter is better. I'm looking at 285-30/r18. My use has a mix of mid second gear courses, and mid 3rd gear courses. Both would benefit from lower gearing, and lowering the car an inch within the rules is a bonus I'll gladly take.
  15. Budget 18" wheels for F Street on a 2017 PP1 GT

    I've done some searching. I'm sure the answer is here, but I didn't find it. I'm looking to be able to run 18" tires within F Street allowances on a 2017 PP1 GT, partly for tire cost savings and partly for more size and compound options. What are the low budget options that clear the brakes?
  16. Air to Fuel Ratio - What's the Point?

    Drill down one more level and you get a faux analog gauge which displays meaningful information.
