b'Business NoteBuild-Your-Own Versus Design-Your-Own:When you purchase components from RSRT to build your own design of chassis and/or suspension, please do not expect any significant technical guidance.Its not that Ron doesnt want to help you.But buying some shocks,springs & a sway bar kit isnt going to get you a complete Ron Sutton setup for your car.He cant. Its not that he wont.He literally can not tell you what spring rates or bar rates to run in your race car, without doing a 100% complete work up on your cars geometry & setup.Ron likes to say he is knowledgeable about how to get to the optimum setup.But hes not magic.He cant pull it out of his ass. Ron Suttons reputation for designing race cars from scratch & creating setups for race cars that can roll out of the trailer & run for the pole & the winare based on a LOT of work.The entire geometry of the race carfront & rear suspension, steering, ride height, track width, weight distribution, CG, etc, etc, etchave to be input into a racing software program.The software doesnt spit out a setup.It just calculates numbers for everything that matters.The software will calculate static & dynamic information, providing he knows how much the car will dive under braking & roll under cornering.Usually, Ron is deciding on a travel & roll setup strategy beforehand & creating the setup to achieve that.Ron looks at the static & dynamic (on track) result of every important area.This includes the roll centers, caster, camber, toe, bump curves, ackerman, scrub radius, ride heights, anti-dive, anti-squat, motion ratios, wheel rates, total roll stiffness, spring rate to corner rate percentages, roll couple, front & rear lateral load distribution, front & rear roll angles & more.Then, andonly then, does Ron know what spring & bar rates are needed in a given race car.Ron knows what he needs in every one of these numbers to have a car that will literally roll out of the trailer & run for the pole & the win.He has done it over a thousand times.But he has to do the work.That means the racer or team has to precisely measure every pivot point on the race cars front & rear suspension & steering. They have to corner scale the car, as well as help gather dimensions & weights for CG calcs & measure all the tire & wheel data.Ron did this for over two decades.It was called Tech Service #40.In his words, It was a lot of frickin work for very little money. I did it to help other racers & have the pride of knowing my setups were winning in all forms of motorsports. But now Im old.Ive already done all that & the money I used to charge for a Tech-40 service is not worth the time to me anymore.All of this work is ALREADY DONE in every autocross, track & race car package we sell.Every single one.Down to the gnats ass details.If you want a race car that will kick ass right out of the trailer, then either purchase one of Rons pre-engineered packagesor figure it out yourself.But dont expect Ron to figure it out for you when you are buying componentsto build your own design (or someone elses).Ifif you REALLY want Ron Sutton to optimize the geometry & setup for a specific car you have. Ron has grudgingly agreed to do a Tech-40 for $5000.It will take 2-4 months of back & forth between you & Ronand a lot of precise measuring on your part.It is not a quick deal.23'
