Loving the 2021 GT500, but honestly a little underwhelmed on the exhaust note. Curious if others have done the resonator delete, and if so, opinions on the changes in the exhaust note. Looks like Lethal Performance makes a great resonator delete. Anyone gone that direction? Also, thoughts on...

Considering getting my 350R PPF'ed. Have a quote from one reputable installer. Entire car ceramic coated plus majority of the car PPF'ed - quote was $6,900. The PPF material will be XPEL. Price seems a bit steep to me. Now, I am considering only getting the front, fenders, mirrors, and A pillars...

Getting my 350R PPF'ed and the technician (who does many high-end cars and also done multiple 500s and 350s) said that he will remove the OEM stripes, apply PPF material across the entire sections, and then re-apply new racing stripes after the PPF is done. Question - suggestions /...

The other day (magically after I left the dealer for an oil change and brake flush), my 2020 GT350R (4k miles) is showing check engine light. Used my OBD II scanner, and it is showing DTC code P0128. Relates to coolant thermostat / coolant temperature. I believe other 350 / 350R owners have...

Picked up my new 2021 GT500 on Saturday. Car had 7 miles on it from the dealer. So far, I've accumulated a whopping 50 miles on it. I wont be able to complete the full break-in period until spring / summer 2022 (cars get stored for the winter in the next month or so). My understanding is...

It was bound to happen sometime. I traded in my 2018 Roush Phase II Supercharged GT (Kona Blue, manual) with 6,400 miles on it for a new 2021 Shelby GT500. While it does not have the CF track pack (which is OK - I have the 350R), the GT500 does have the optional handling package. Bringing her...

Does anyone know what standard / OEM cooling equipment would have been installed on a 2018 Base GT with PP1 and dealer installed Roush Phase II supercharger? For example - engine oil cooling, engine head cooling, transmission cooling, and rear differential cooling? My car has the rear diff...

So I ordered Project 6GR FIVEs as the spare / extra set of time for my 350R. Installed yesterday were Goodyear Supercar 3Rs, 305 fronts and 325 rears. Gonna try the Goodyear 3R tire out and see how I like it compared to the Michelin SC2. The Project 6GR rims for the 350R are supposed to have...

So the combo of the LT headers and Flowmaster Outlaw exhaust has proven to be about the loudest option I could have put on the 2018 Roush Phase II SC mustang (see mod list in sig). Contemplating doing a muffler swap to something a little more tame and less thunderous than the FLowmaster Outlaw...

First off, really appreciate the great info from other members on track tire options / comparisons outside of the Michelin Sport Cup 2s. I'm going down the Goodyear Supercar 3R path for the spare rims and will give them a try. Others had great feedback on this tire, and it's a little cheaper...

Is the Hunter Revolution the appropriate touchless tire changing machine that is needed to mount and dismount the tires from the 350R carbon fiber rims? Thanks.

I posted this in the Shelby forum and did not get much traction (no pun intended). Hopefully I'll get more feedback from track drivers in this forum. After multiple track sessions this summer, my OEM Cup 2s are cooked and time to replace the tires. Curious if other R owners have tried different...

After multiple track sessions this summer, my OEM Cup 2s are cooked and time to replace the tires. Curious if other R owners have tried different rubber than the Michelin Cup 2s, and if so, would you mind sharing your experiences. Also, anyone running 325s in the rear as opposed to the 315s? If...

Scheduled to hit the strip this Friday evening for test-n-tune night, weather permitting. Forecast unfortunately is not looking good. Been a loooooong time since I hit the strip, and the last time, it was a 400 rwhp 1999 SVT Cobra (Nitrous) with a 4.10 rear-end that ran awesome. But that is...

Got the 2018 Roush Phase II SC GT on a dynojet today. See mod list in my signature. Was a very hot day for NE Ohio in mid-May (mid 80s today). Car put down 706 rwhp and 626 rwtq. I ran two 32 ounce cans of Race Gas Ultra in the tank today, on a half-tank of 93. So octane should have been around...

Headed back to the road course in the 350R soon. Gonna bring my Dad with me to track in June. He has a mildly modified 2014 GT (exhaust, intake, tune, lowered, wider rims & tires with Michelin Pilot Sport 4s). The Michelin Pilot Sport 4s should be fine for his car's capabilities. This track...

See link below. Chassis # JR368. Nothing mentioned in the notes or pics about the absence of the CF rims. In fact, the spec sheet states CF rims (" 19 x 11 Fr & 19 x 11.5 Rr Carbon Fiber"). Hope someone does not get burned on this car...

Did my first track experience in the 2020 350R on Wednesday at Nelson Ledges Road Course in Garrettsville, OH. Weather conditions were less than ideal. Had light to mild rain in the morning until 10:30 am and temps were in the high 40s. Track time opened up around 9:30 am. It was still raining...

https://www.roushperformance.com/2018-2021-roush-supercharged-max-cooling-upgrade.html?mc_cid=08459f0d92&mc_eid=2a12c772ef What does everyone think? $2,100 for the kit. I talked with the very experienced mustang / Roush tech at my Ford dealership today (super awesome and knowledgeable guy)...

I am having these SVE 350R 19x10 front and 19x11 rear rims installed on my 2018 Roush Phase II SC GT later this week. 285 Pilot Sport 4s on the front and 305 Nitto NT05Rs on the rear (I am using my existing Nitto NT05Rs and will be switching to a stickier tire after I burn these out later this...
