Performance Tuning Guide for a 1970 Buick GSX Stage 1 by Sam Mods

This handling provides realistic top speed, power, gear ratios and center of gravity for Sam Mods 70 Buick GSX add on.

Version 2.0 (pending) finally makes a couple of important updates for realism now that I know how to do them including the ability to coast/free roll without throttle, removal of ABS which should not be on a classic of this era to begin with, fixed the stupid Rockstar wheelie update, major improvements to the general physics/handling behavior of the car were made and I've also included improved tire, brake rotor and underside textures to make the car look more realistic. The tire texture replaces the modern winter/gravel white wall tire with a black wall BFG more appropriate for a muscle car. The rotor texture is made from a picture of a stock Buick Skylark GSX brake rotor and fits the look of the stock wheel much better than the custom tuner looking rotors it had. The new underside texture slightly improves the bottom of the car in the event it is seen briefly in a jump or rollover etc.

I tried my best to make this car and Dragon777's Chevelle handle very similar to each other because they are sister cars in real life and are built on the same body/frame platform. In real life and in my handling files the Buick drives much better because it has better suspension, factory disc brakes, a lighter engine and better aerodynamics. However the Chevelle has more HP and a lower gear. The lower gearing means the Chevelle actually has less top speed despite the extra power but that low gearing gives it brutal acceleration which makes it ideal for drag racing. In short, the LS6 454 Chevelle is best suited for drag racing and the Buick GSX is a more expensive, more refined version that does everything else slightly better including top speed.

GSX 455 Stage 1

• 400 HP
• 120 MPH
• 5.8 Second 0-60 Time
• 13.38 Second Quarter Mile

With a proper set of performance tires or simply raced at a fully prepped drag strip an otherwise stock GSX Stage 1 is capable of high 12 second runs and significantly improved 0-60 times.

Inverse power by IKT is a "must have" mod if you are sick of the game letting off the gas for you in the middle of a slide.

My realistic surface traction overhaul mod is another must have for a more challenging and realistic driving experience on all terrain types.
