Racers: Did you install new adjustable shocks and now your lap times are slower? Do a "shock scan"! Note current adjustment settings Set bump and rebound full soft Do an out and in lap Add bump in two click increments until "feel" improves Now add rebound in two sweep (or click) increments until car "feel" [...]

Lance writes: Need help with an SCCA EP 240Z with custom Moton 2 way remote shocks on all four corners. McPherson front so motion ratio = 1? 350# front springs 225# rear. Would like the car to turn in better and it is loose on exit. First year with car could not get the shocks [...]

"Why are Ferrari's so "soft"?" is a question I get all the time, given my experience with the beautiful red cars... This term is relative, IMO. Ferrari's are no softer than most other road going cars, even other sporting automobiles. Suspension design is all about compromise with a road car. The environments change, the market [...]

How large of a range of adjustment is available from a Bilstein? A question I get all the time; here's a quick shot of force vs. velocity data from an original equipment Ferrari F355 shock: This data shows four shocks set full stiff and one then re-tested set to full soft, which opens the adjuster [...]

Manually adjusting shocks: Ferrari F355, 550, 456, Mondial T This likely applies mostly to the F355 crowd (due to popularity) but technically also applies to the 550, 456 and Mondial T as the shocks have the same active damping system....

Here's a primer for what to look for when your dampers are getting tested and you're sweating, not knowing if your championship finishing position will stick or you'll be penalized as there's a [...]

The following is what I recommend as a starting point when tuning your F355 for the race track, this set up is optimized with either F355 Challenge suspension or my "sport" system for road cars or my "track" system for dedicated track cars: When setting up the F355 with the new (revalved) shocks and springs [...]

Hi Rob, I have Penske doubles. I vary bump and rebound to suit the track, but I always set my canister pressure pre-race weekend at 150 psi. Are there reasons to change canister (nitrogen) pressure? [Always asking questions....] Peter You can use it as a tuning tool but first must wrap your mind around what [...]

By Rob Schermerhorn Sometimes the least expensive modification is the most rewarding. Certainly, lowering your car not only improves appearance, but also performance, especially at the racetrack. You may not know this: your Ferrari is already built for ease of ride height adjustment, that's where the low cost comes in. The procedure is straightforward. Before [...]
