    I believe I mentioned it is a hard challenge bushing (white). You can go challenge bushings all around if you want, but my latest discussion is more about finding a softer bushing solution.

    Good work Ken, you made the more hard...
    You have always your OEM manifolds ?
    Install tubistyle
    Try to see if your bushings are always softer behind.
    Is it possible to see me where is the pump for steering rack, i think in front of the motor...

    Not my car above.


    But yes I still have OE manifolds, which were the upgraded version purchased by the previous owner in 2005. Has about 13k mi and seems to be doing ok for now.

    Ferrari standard car sway bar bushings for 355 have always been rubber (red). But who knows, maybe I’m open to challenge bushings.

    So when is someone going to install the FHP on their Berlinetta and give us a report ? This thread has been going on for a longtime. Lets hear some results.

    Ferrari used 3 different sources to produce springs during that time. But specs should be the same. Keep in mind the rear springs is a 512 TR spring.

    As a gentle reminder to those installing FHP on MY1994 and 1995 cars, it's important to upgrade your front shock mounts. The sheet metal up there is ~1.5mm thick and prone to cracking if you install upgraded springs.

    See these threads:

    My track day experience

    H&R versus Fiorano Springs

    What suspension parts (if any) to replace at 46K miles to improve handling


    Beginning with MY1996, the sheet metal and shock mounts were beefed up on production cars and the Challenge updates were no longer necessary.

    Pete (bobzdar) made preliminary modifications on his 1995 Berlinetta (my car's sister) and Elliott (MAD828) did the full upgrade: 1995 F355 GTS: Restoration and Major Service

    I actually had this issue after installing coilovers on my 95. The towers were subsequently reinforced, but it’s interesting to know that this common.

    If you have a 95 and actually drive it, it will require it. Glad I did mine, and I can say for sure the addition of the Fiorano parts, rebuilt shocks, bushings and the challenge reinforced uprights were the best money spent on the car.

    My 2200 lb/in front Challenge springs caused considerable damage as you saw in the pictures I posted on those threads. My car never had the shock mount modification when it raced in the Challenge Series.


    Right, Elliott. Pete was beginning to see similar damage with his H&R springs. That's why I feel that anyone planning on upgrading springs on a 1994 or 1995 car should have the Challenge shock mount modification done.

    Yes, and on your 1999 car it will look just like the one on this 1998 F355 Challenge...
