I need GTS Alignment specs

[Jaymz]

Hello,
I need to get the preferred alignment specs for my 98 GTS. I would like an aggressive setup for road course tracks such as Mid-Ohio or Putnam Park. I have revalved shocks, modified springs, and different wheels 325X30X18 front and 335X35X17 rear.

Thanks in advance.
James

I'll offer you a range of acceptable values, however, the optimal set-up depends on the track you are at, the type of tires, driving style and experience level, etc. etc. These should get you in the ballpark. Use a tire pyrometer religiously when you are at the track to determine what tweeks you will need to improve on these specs.

CASTER: Front- 6 to 7 degrees (positive)
Rear- 1 degree (positive)

CAMBER: Front- 2 to 3 degrees (negative)
Rear- 1 to 2 degrees (negative)

TOE: Front- 1/32" to 3/32" (toe-out)in each wheel
Rear- 1/64" to 3/64"(toe-in) in each wheel

A proper 4-wheel alignment requires a Viper essential tool called an inclinometer. Make sure you set your corner weights and ride heights, and have your race tires inflated to their proper pressure before doing the alignment.

Don't drive your car on the street with these alignment specs unless you have a huge tire budget.
