Brand new, never mounted on car. MRR M600 19X10 and 285/35-19 Bridgestone RE71Rs. Purchased from Paul at PK Auto Design last month. Includes TPMS, road force balancing, and tuner lugs. No spacers need for this square setup. Perfect for the track! The reason for selling is that I traded in...

Hi all, I’m hoping to have some of the engineers in the house comment on this please. Generally, is piston slap an “operating as designed” condition and does it shorten the durability and reliability of an engine? Additionally, are hypereutectic piston engines more likely to exhibit this...

Hi All, I’ve a concern about the tuner lug nuts that must be used on aftermarket wheels. The lug nuts that came with my wheels are the fluted type and are Kosei branded. Can these handle many on/off cycles without the fluting getting chewed up? I’m using these new wheels for track duty...

So, I was running at Palmer yesterday with an ambient of about 80-85. The second session out and a few laps in, my car started to cut power, very drastically, where it was totally dead above approximately 3k rpm. Limp mode. CHT was good, about 235, oil temp was about 220. I have a Mishi...

Wasn't sure whether to post this here, or in the road course sub forum! A lot of folks in this forum run different exhaust setups; some folks go to track days. Many (most it seems) tracks enforce a sound limit at 50 feet, and the town or the track will place a sound meter at undisclosed...

Hey Ford, bring back Anniversary Gold as a Mustang color. :amen: http://www.cjponyparts.com/variants/mustang-anniversary-gold-edition

Hi, I've been unable to find steel wheels for our Mustangs. I'm looking for cheap trackday steelies. Do these exist? 18X10's preferable.

Hi fellow New England Mustang Owners, I often run at HPDE's with COM, http://www.comscc.org/ ..and I have to say that I always have a good experience with them. The instructors are pretty good and the events run smoothly and safely. For the past events I've run with them over the past...

Hi All, Hoping you can help. What is the easiest/best ingress point on the firewall to run a wire from the engine compartment to the interior? I plan on installing an oil temp gauge and need to run the sender wire. Thanks!

Hi all, I've pulled the trigger on a Mishimoto direct fit oil cooler and a Mishi radiator for my non-PP GT. The last few times on the track, CHT temps were getting up there. Many OP's say that the oil temp and coolant temp gauge temps are calculated and I'd like to install a true oil temp...

Surprise! :shocked: Another thread talking about the clunk/rattle from the rear of these cars. I've got the BMR CB005, Steeda Jacking Rails, Steeda Billet Shock Mounts, and Steeda non-adj Struts and shocks. The clunk/rattle - let's say crattle - only happens when the right rear wheel goes...

Hi, I'm attending HPDE at Palmer with my S550 GT. I have Magnaflow MF mufflers on stock exhaust with the stock resonator (sounds great BTW). Palmer track rules state that the sound limit is 96db at 50ft from the edge of the track. Does anyone run their cars there with aftermarket exhaust...

Just curious, Anyone running an auto trans GT on HPDE days? I'll be running mine in a few weeks and am curious to hear about any experiences with this vs a PP with a manual trans. I'll also be swapping out the stock 18's with all season rubber for 19" factory PP wheels and summer P-zero's...
