Tech Help

The key to high performance handling is a top quality suspension system. Proper chassis adjustments and properly balanced tire pressures.

Aim for the theoretical ideal, neutral steer. Neutral steer is matched front and rear traction.

Understeer is a plowing or pushing effect when cornering.

Oversteer is the rear sliding outward on turns.

Adjustments To increase Understeer To Increase Oversteer
front tire pressure lower higher
rear tire pressure higher lower
front tire section smaller larger
rear tire section larger smaller
front wheel camber more positive more negative
rear wheel camber more negative more positive
front springs stiffer softer
rear springs softer stiffer
front anti-sway bar thicker (stiffer) thinner (softer)
rear anti-sway bar thinner (softer) thicker (stiffer)
weight distribution more forward more rearward

Polyurethane can be noisy if done WRONG.

WRONG #1 You cannot blend anything into Polyurethane. Not even Graphite! Nothing like this works because the family of Urethane plastic does not like impurities.
(the word Polyurethane means blends of different Urethane plastics)

Graphite does not work for a couple reasons. If you put just a little in the Urethane then the graphite is fully encapsulated by the Urethane and the Graphite never touches the metal sway bar or a-arm shaft. If you add a lot, then the Polyurethane falls apart because it does not stick to the graphite (remember, graphite is a slippery lubricant). You might as well throw handful of dirt into it.

Wrong #2 You cannot put in a grease zirk and tell people to grease it.  Polyurethane must have the right lubricant to make it quiet.  There are some lube greases that are bad for Polyurethane.  So there are all these greasable bushings caked up with the wrong grease and the Polyurethane bushings are still Noisy.

The correct lube is sent by PolyBushing.ca with every kit that needs lube.  It works, it’s green, it’s sticky…and need be applied only at installation.

Wrong #3 You cannot cost reduce your Polyurethane products and expect a long and quiet life. Polyurethane is like anything else important to you. It comes in many different grades. Polyurethane can be designed and tempered a lot like steel.. If you design it to cure too quickly it becomes harder. Harder Polyurethane is Noisier. Shorter molding time means less cost. So between the correct chemistry and mold design, it costs just a little more to do it right. But it sure pays off.
