You may be able to lower the car, but you will still carry a 400 lb. weight penalty. Also, Challenge wheels are much lighter, reducing unsprung weight, but will crack on rough streets in no time. In addition, the brakes on the Challenge are monstrous compared to the street car, and the discs and pads don't work well until they are really warm, so I wouldn't use them on a street car either. If you want a really fast turn-in rate put on slicks and drive in the rain. Tried it this weekend at the Glen. Can't wait to get the bill for that one. Why do you really need a faster turn-in rate? Do you track this car? | ||

There was an article in the Dec 02 Forza about Digi-Tec tuning a 360 spider. I thought is was pretty interesting so I saved it. According to Digi-Tec the stock suspension is height adjustable, and they lowered it 25mm all around. You might want to see if you can get a copy of the article, or I'll be glad to fax it to you. | ||

Those camber figues don't cause excessive tyre wear. Std road 360's wear out the outside edges on the front when pushed hard, so whether the tyre is scrap because the edges are worn, or because the whole tread area is worn.....scrap is scrap. But this way you get better value, more grip and sharper turn in. The safety element of understeer is built in, but can be tweaked out easily. Challenge cars run chassis ride heights of 88mm front, 110 rear measured at the flat underside of the chassis rail near the most forward pickup each end. They have up to -4deg Camber front and about -2.5 rear. They have Toe of 0 +/-1mm toe on front, and 2mm in each side rear. They are the factory figues. Most racers lower them even more, down to 70 front, 90 rear is not unusual, but means they end up riding on the bump stops all the time....fine if you're driving on a perfect surface, crap if there's so much as a ripple in the road. In our mixed category in Oz we're allowed to fit different shox, so the std challenge, non adjustable, non active Sach's go straight in the cupboard and I fit 4 way (LSB, REB, HSB, CAN) adjustable ohlins TT44's. Easily find 1- 1.5s per minute at most tracks, the more bumpier, the higher gain. Always put more rear toe in on too, and camber gets tweaked after checks with the tyre pyro at each track. | ||

Hmmm... Robert - basically Ferrari of Houston are going to upgrade your car to a Ferrari 360 Stradale right? Novel way of looking at it? | ||

You don't need to spend a fortune to make huge improvements to your road 360. Set front camber to about -2 to -2.5, set front toe at around 1mm total in and lower it at the front as much as you like within reason, but about 10mm lower at the lower pick up pivots makes a nice difference. Leave the rear alone, or crank the toe in up to about 6mm total IN to help braking stability and reduce over steer. You can lower the whole thing if you want, but the 360 has quite a lot of camber gain and bump steer which worsens the lower you get, and with soft springs, the extra travel causes instability. The challenge cars are low, but have limited travel on their approx 1250lbs front and 1650lbs rear springs. | ||

What's the whole package ? Or is just lowering and setting-up the suspension ? | ||

Sounds like you're living your dream. Why did you pick Ferrari of Houston over a dealer closer to Indiana? | ||

Just FYI, I am having Ferrari of Huston give me a challenge type set up on my 360 street car. They are not going to lower the car all the way to challenge specs, but the tech told me he would give me a set up that would be streetable but look lower, and have a faster turn in rate. |
