The measuring itself, depending on the environment and preparations, may not take more than few minutes, but it would best if the car is sitting on a flat, even surface, like on garage/shop floor or 4-post lift ramps “fully loaded”, i.e. If any owners and/or caretakers would care to measure, record and provide me their findings, it would be very helpful. I’m preparing to help Jim get his 330 GTC suspension ride height and other related things sorted, but before getting started I would love to get some reference from other cars, mainly their “ride height” measurements/readings. After the ride height is corrected, you will need to re-align the suspension as the change in ride height will change the alignment. Amazingly, once an original GTC spring takes a set, it seems to stay there, so I would bet a set of spacers to restore the ride height will make the car correct for many years.Ħ. You may have to do some measuring to get the correct motion ratio for how far the shock travels versus wheel travel, to determine the thickness of the spacer needed. I believe new springs are available today, but in the past, we machined spacers to place on the lower spring mount over the shocks. If you have sagged springs, all is not lost. I would highly recommend staying with the factory ride height.ĥ. They picked the factory ride height for a reason. Ferrari, in this era, had very smart engineers. This means you probably have sagged front and possibly rear springs, or the rear upper shock mounts have broken away from the frame. I am not aware of a easy way of lowering a GTC suspension. As others have mentioned, a lower ride height will bring a myriad of problems with it.ģ. People today will immediately discount a car with obviously wrong components.Ģ. The funds spent for the correct wheels and tires will easily come back to you when the car is sold. However the other posters have given you good advice.ġ. Jim: Remember, opinions are like armpits, everybody has them. Stay with 205/70 tires and set the rear ride height to level the car.Ģ. (Also, I just bought new fronts because I thought the 80 profile tires wouldn't be available for quite a while.)ġ. ![]() Of course, thought must be given to the range of travel and alignment of the suspension. I have always had improved handling when lowering a car, because of the lower center of gravity. ![]() ![]() I plan to set the height with a couple of my buddies sitting in the car, and with a full tank of gas. My plan is to stay with the 205/70 tires, keep the front at its current height, and adjust up the rear to match. A drawback of the 80 profile tire is that the car will lug more when taking off as it has a very tall first gear (but the engine runs at lower revs at freeway speeds). The 80 profile tires are over an inch and a half taller, which would require a higher car to make room in the wheel wells. However, TTR does have custom spacers for the coil overs so I can go whichever way I finally decide. TTR (Timo) is recommending that I go all the way back to "original" ride height and invest in the correct tires. Jumprun here on FChat recommends staying with the 205/70 tires - better handling. The rear is somewhat lower, and the suspension hits the stops sometimes, with the exhaust dragging on bumps. I've seen from posts on other cars that most people fit the 205/70 tire because it is more readily available.Īccording to the specs in the Angelo Wallace manual, my car has been lowered about an inch in the front. I later learned that the correct tire is the 205VR14, which is an 80 profile tire.
