    I am interested in putting the FRPP Aluminum Subframe bushings in my “mostly” track car. Are these overly harsh on the street?

    The alternative is one of the various cradle lockout kits, but those seem like a compromise compared to this setup and the diff bushings.

    I have the FP diff and cradle bushings.
    If you are doing a mostly track car do the FP bushings.

    If you worry about any interior noise use the other brands lock outs.

    This is mostly a track car, but will be driven on the street as a second car, nice day car.

    How much NVH is added with these? Full race car levels of unbearable or just marginally worse?

    This car will likely see less than 2k miles a year of street time.

    2000 miles a year I’d go with the FP bushings.
    I made a cradle to drop my Irs out. [​IMG][​IMG][​IMG]

    Scott, Thats the professional way to do it. I used a couple floor jacks, wood blocks and 4 jack stands.

    Holy crap that’s awesome!

    Not sure if you’re inclined to rent that, but I’d be happy to do that if you’re interested.

    I can make you one if you like.
    It’s fairly cheap and easy. I was going to make it from tubing and weld it but I ended up making it from uni-strut and bolting it together so I could disassemble it and store it.
    I’d lend you mine but I’m currently using it again.
    I can also give you dimensions if you like. Totally up to you.
    You can contact me at 4193897673 if you like.
    Scott.

    I get you a parts list and measurements.
    I bought the uni strut from a local distributor but I know it’s available from menards and Home Depot.

    Used Full Tilt Boogie spericial bearings, adjustable camber arm, adjustable toe arm and FRPP aluminum subframe and diff bushings. Works great

    Under hard acceleration or braking on the track you could feel the rear dancing around a lot. This cured the problem.
