Peter -- I was running 2-3 mm toe-in on my ex-'78 (w/QV wheels). The reason I wanted to go to -2 deg camber at the front was that even at -1.5 deg camber I was still getting a little more wear on the outside edges of the tires than on the inside.
PS I found the most even rear tire wear at about -1 deg camber. |

Wow, some serious work here Steve.
Thank you very much for your information and links. I will talk to Christos at my garage on Monday.
How much toe-in do you have at the front when you are running with -1.5 deg camber and what happend to the tire wear?
Thanks again

Hi Peter � �easy� is a relative term, but I think you have three options to lower the front coachwork as described in this earlier thread:
http://www.yourlog.com/discus/messages/21/928.html?
A group of FerrariListers are in the middle of having the modified lower spring perches made -- see
http://www.happyisgood.com/perch
for a discussion.
Also, I�ve noticed that there�s a (seemingly constant) ad on eBay for a complete 308/328 �kit�:

Maybe, the seller can be a resource for you if you only want ride-height adjustable front (non-Koni) shocks.
With regard to front camber, I ran about �1.5 deg and would like to have gone to �2 deg (but �1.5 deg was the max possible negative camber without making longer threaded studs on the A-arm mounts).
And finally I think the �spacer� you see is the rubber insulator between the spring and the lower perch � probably best left in place.
Good luck with the project. |

Hi all.
Next week I will put new tires on my 328 GTB �88 euro, probably Yokohama AVS Sport 225/50-16 and 245/45-16. Recommended width is 7� and 8� respectively so I think it will be OK. I would also like to lower the front 1 � 1.5 cm (1/2�) to gain high speed stability (someone said to me), anyway, the car seams to lean backwards a bit. Does anyone have any suggestion on how to do that in an easy way? There is a spacer under the spring. Can it be removed?
I will also redo the suspension set up. Primarily, I want to gain cornering performance without loosing too much breaking performance and stability. A little more oversteer is OK. I have Pirelli P700 at the front and P7000 at the rear for the moment, maybe that is why the car understeer a bit. I will use the car on smooth roads, occasionally on track and I do accept a slightly higher tire wear.
Standard setting is:
Front
Camber: -0°35� - -0°55�
Toe in: 2 - 3 mm
Caster: 5°30� - 6°10�
Rear
Camber: -1°50� - -2°10�
Toe: 3 - 4 mm
I suppose there are a few roadholding gurus here. I would be very grateful if any of you could comment this and perhaps suggest another set up.
Mille gracie
Peter |
