Some of the upgrades that I've already make to my '87 Avanti include; Performance Suspension Stage IV kit, front frame bracket, 16x7 wheels and tires, drilled and slotted front brakes with two piston calipers, 2" drop spindles and a Cat-back 2 1/2" exhaust system.
I could use any recommendations for some of my next upgrades -
1.) Rear disc brakes - have 2 different systems available in 11", 12" or 13" rotors.
2.) Serpentine belt drive - GM Performance offers a complete bolt on system, it would also switch the alternator with the A/C compressor moving it to the passenger side of the engine. Would really clean up the engine compartment.
3.) Remove belt driven fan and install electric fan system - Current system makes alot of noise, would love to get the noise down to the gentle wind blowing by the window seals.
4.) Vintage Air heating and cooling system - I have never seen a bigger mess then the cobbled up heating and cooling system in this car. Well... the wiring comes close.
Upgrades - comments welcomed
in 1984-91 Avanti
