b'TECH TIP PAGE Tech Tip 39: Veteran Racers & Crew Chiefs hate guessing or winging it at the track. The smarts one work to be very prepared. They count the threads per inch on threaded adjusters throughout the suspension to know how change adjustments make.They will adjust ride height exactly 1.00, with the shock jack screws, and count the exact number of turns it took. Now they know precisely how much change to expect from a full turn, partial turn or multiple turns. No guessing. No surprises. At the shop, they also do this with the car on the scales to measure & record corner weight & cross weight % changes. Same with the 3-link (anti-squat) adjuster, Watts link, sway bar links, tie rods, etc.If you take the time to do this, track tuning is quick & predictable. Winning Crew Chiefs know exactly how many turns it takes to adjust EVERY area of their race car. Knowing that a full turn of each shock jack screws gives you X% of cross weight changeor 3 turns on the top link is X% more or less Anti-Squator 3 turns of watts link adjuster changes the rear roll center 3/8is powerful knowledge to your tuning game at the track.Tech Tip 29: Designing race car suspensions involve many factors. Somecomplex. Some straightforward like understanding shear. For example,when you mount a bolt in double shear, it is literally supported on both ends,cutting the shear forces in halflike the example inside the red circle here. When you mount a bolt in single shear, like the blue circle, we are putting allthe shear forces trying to bend, break or shear the bolt off. Thats OK if wehave a strong enough bolt. RSRT utilizes 5/8 170KSI bolts (rated at43,500#) for all single shear lower shock mounts front & rear.Tech Tip 42: Rookie racers tend to want larger tires in the rear of the car to help grip under power. If the car has 50%+ front weight, that is a bad choice. When targetingneutral handling balance, we actually need the tire size to match the cars front to rear weight bias.For example, Indy Cars, Formula Cars & Sprint Cars, have around 60% rear weight & 40% front. So, they need 60% of the total tire contact patch area in the rear & around 40% in the front. And you see this size difference on these cars with the huge rear tires & smaller fronts.Rear engine cars, or simply rear heavy cars, need tire contact patch area in the rear to match the cars rear weight bias. If there is more rear weight, the car needs more rear tire. If the tire sizes dont jive with the weight bias, achieving neutral handling balance is a harder job.In full bodied, front engine cars with 53% to 58% front weight bias, we actually need larger tires in the front. But no one does this. For this reason, running wider rear tires is not only of no benefit, it actually makes the job of achieving handling balance harder.So lets leave the monster rear tire sizes to the drag cars & run the same size tire on all four corners. Well go faster & have an easier job of tuning your car for neutral handling balance.898'
