Thanks!

The Boss 302 Supplement to the owner's manual that came with my car lists the friction modifier as one of the part numbers for the fluid in the diff. What's up with that?

My local Ford dealer recently replaced the pinion seal and both rear axle seals under warranty. At that time, they neglected to add the friction modifier to the diff fluid. My questions are these: 1) What should the diff operation typically feel like without the friction modifier? 2) How long...

This is my 3rd season using PSS (265/40ZR19 front, 295/35ZR19 rear). For me, they are happiest at 33.5-34 psi at the end of the session (hot pressure). At this pressure, the car is well balanced and grippy, tire temps are smoothly gradient across the face of the tire, and tread roll off is...

My car's driveline is bone stock and it has always displayed this issue.

My car has always displayed what I call a slight "surging" between 2-3000 rpm. It feels to me like a subtle manifestation of inconsistency that equates to a hot cam or a very minor version of the jerking that the car can suffer when coming off throttle in first gear, then getting back on the...

Geely has done a pretty good job with Volvo so far, FWIW.

What wheels are you using? I agree with switching sizes; I use 265/40 19s on the front and 295/35 19s on the rear on stock rims. In the PSS, this size was made for a BMW, but Chevrolet is using the same size on the C7 Corvette (at least on the rear). I just ran a track day at Road Atlanta with a...

Roebling Road is a great track to learn about how your car handles. It's also good for driver skill development, with a variety of turns and lots of runoff areas. Road Atlanta is terrific, but can be unforgiving. Barber is like a big autocross track; there's always something going on. There's...

The product I am using with success is called Wheel Brightener XD. It's provided by Atlanta Detail Supply. They are a wholesale supplier to dealerships, body shops, etc. Here is a link to the product: http://shop.detaillink.com/product.sc?productId=812&categoryId=15 My detailer suggests a 50/50...

My detailer gave me a new product to try this weekend. It removed about 50% of the accumulated crud after two applications, with no harm to the clear. I see no reason why continued use won't remove all of the deposits (there's the remains of most of a set of factory rotors on my wheels). I will...

Are you running RS-56s on the rear? If so, then the residue is likely as much rotor material as pad dust. I have found no way to remove it short of lacquer thinner, which will harm the clear coat. Anything less hot, like mineral spirits, solvents, etc. will have no effect. YMMV.

Since SCBoss seems to have set the market with his bracket, price drop on this unit to $125 including shipping in the continental US.
