Suspension Settings...

Post by PietereQ » Mon Jul 25, 2011 12:10 pm

I have been thinking about it for a while, and I came up with such idea... This site is and has been great for it's users sharing their knowledge and experience with others, and how about a talk strictly devoted to the way, we set our cars so we can pull as much lat. G's as we can with our transaxle alfas. :?: I' know that it's often of personal preference the car behaves but we can all agree, that gtv6 that scrubs it's side mirrors when cornering isn't going to make good times on track rignt? I just thought it would be very useful to store that knowledge in one topic so it could be easily found and analysed at any time

Since I'm a newbie racer, and I just have recently brought my car to the point, that it can be more or less properly set for cornering, I wonder what you think abut this setup:

Car: GTV6
Engine/power: 2,5 so far stock'ish
Weight:~1100kg
Wheels/Tyres: 215/45 R17 semislick

Spring rates:
Front: 160N/mm
Rear: 70N/mm
30mm adjustable front AR bar
Stock rear AR bar

Front static camber: 3-3,5 degree?
Caster/CastOr :mrgreen: 8 deg?
Toe out front 1 mm?

I'm not touching the de Dion at the moment, but planning camber and toe ofc.

Soooo... how bad/good is it as a settings for starters?

Giulietta 2.0 TS
- stock 75 TS engine and box.
- TS driveline with upgraded brakes ( volvo callipers, 25,4mm mastercyl.)
- 2,5-3 degrees camber.
- 0 toe in/out.
- max caster, believe it was like 9 degrees.
- casterball mod.
- 28mm AR bar at front stock rear.
- 16" with 195-45 and 205-45 tyres.
- lowered with stock torsion bars (2 teeth) and springs.
- yellow koni all around, almost fully closed up front and halway closed in the back.

Very much grip and very neutral going into slight oversteer when pushed hard. Not very comfortable however. :wink: Very exciting to use as my daily driver, very dangerous for my license... :oops:
Drive it like you stole it...
