Ive got an 89 LS and just bought the 27.5mm torsion bars from upgrademotoring. Does anyone know if these torison bars require modification when it comes to dropping the car? im looking to go no more than 2 in on the drop. ive heard that you can lower it on the stock 19mm torsion bars but you have to modify them by filing the key spline in some way...
