Sorry if this has been discussed at length but I can't find any comparisons between the MMR and FTB cooler kits, why the large price difference, and any other pluses and minuses, reliability, etc. Thanks for any inputs guys, new to this forum. FYI I track So Cal 7-10 times a year even in the hot summers, so this is a very needed upgrade. 2019 PP2 stock....for now.

Have you wrapped and sealed your exhaust a couple or 3 feet on either side of the diff? Tried Motul Racing 90/140?

It helps....and is very cost-effective.
Thanks a bunch, will do those first, and monitor if I need the cooler setup right away. At least hoping cooler winter temps help.

FTB is a quality kit and a friend of mine has the kit installed in his base 19GT. I went with Kenny Brown kit as I have a P1 and didnt need the diff cover. Both systems work well in Texas heat at our local track in Houston. No more IRS limp modes.

For your Kenny Brown kit, you had to drill holes to mount the fan onto the tire well, right? That's all the fab needed?

On another thread somewhere here, I heard about Millers Oils CRX LS 75w140 NT+ I tried it and it is so far the best oil I have found. Developed for F1 and Indy Car. The gear whine was drastically reduced too.

Drillled holes to mount cooler/fan with supplied brackets and a few brackets of my own to mount the cooler in different location off the plastic box and to body of car. Some basic relay and power source wiring included. Its a minor puzzle project for placement.

HYE POWER..

I see that you purchased the MMR kit.. I have one on order, so in the same position as you were in December.
Does come with instructions, wiring schematic, fluid connection layout etc..?
Have you installed yours yet.?
Any advice or tips would be appreciated. I have just completed Battery relocation to the trunk in preparation for the install.
