b'Shocks lets talk shocks There are few places we never want to cut corners on with performance & race cars. Along with safety & brakes, shocks are right up there at the top. No other single component can have such a positive impact or negative impact as the shock absorber, aka Dampers as they are called in Europe. What a good shock can with the right valving can do for the handling of your race or track car is mind boggling. Check out the story later in the catalog about what we achieved with a GT Endurance Road Racing Team with the right shock and valving changes. There are a lot of things that affect the total performance of the shock.Materials & ManufacturingDiameter of Piston Quality Control Piston Design & Weight Internal Shock DesignBleed Circuit Seals & Surfaces insideShock Oils/FluidsValving StrategyAs complex as that soundsits really quite simple from my perspective If the Internal Shock Design is inferior, it doesnt matter what else we do.We can make an inferior shock better or worse than it was, but was not make it a superior shock design. Old Twin Tube design shocks respond in 25-30 milliseconds. That sounds fast, but its quite slow.Well designed Monotube Shocks respond in about 5-6 milliseconds. Thats FAST.And we need the shock to be fast responding, because the asphalt surfaces we run on are NOT flat. No track is flat. If you & I grabbed a flashlight & a 10 straight edge & went to the middle of any corner of any race trackwed see 4-7 undulations in that 10. At autocross cornering speeds of only 34 mph, wed need the suspensionand the shock CONTROLLING the suspension to respond 4-7 in 2/10 of a second. If notyour tire is simply skipping from top to top of the undulations. No issues when the car is straight. But when youre corneringas hard & fast as you canthe instant the tire loses grip, that end of the car takes off toward the outside of the track. On a road course, with a 68 MPH corner, were asking the shocks to respond twice as quick4-7 times in 1/10 of a second. In shortthe responsiveness of the shock is critical for grip. For that reason I do NOT work with, sell or revalve Twin tube shocks. Life is too short to drink cheap beer & race with cheap shocks. Ridetech, Fox, JRI, Ohlins & certain Penske & ARS models are the only shocks I work with currently. Everything else is a waste of time & making your car slower for no good reason. You dont have to spend a fortune on shocks. Stay within your budget. But pass on buying the chrome, double polished, whiz bang unobtanium valveand get yourself some good shocks. The difference in grip is night & day. Regardless of talent or experience, you will be amazed at the additional grip. Grip is your friend. Grip is safe speed. As far as my trick valving goes, I have done it in twin tube shocks when we raced in cost controlled series that didn\'t allow monotube shocks. But we cannot get anywhere near as aggressive with the valving, because twin tube shocks will lock up & skip over the undulations in the asphalt surface. (No asphalt is flat. Nada. None. All asphalt tracks have undulations) For example, the meanest I can get with what we call "zero number" in a typical twin tube . and keep the shock on the ground . is about 150#. Where in a monotube, we run from 600# to 1200# often. Ridetech, Fox, Ohlin, Penske & JRI shocks with my valving are only available through RSRT & my dealers. Single adjustable monotube shocks are the great grip bang for your buck. Adding a base valve to the shock internals reduces the shaft pressure, decreases response time & increases grip for a modest cost. Great value. Going to double or triple adjustable shocks with a canister does the same thing as the base valve, but a smidge better. Cost is more. The extra adjustments dont add grip by themselves. They just make it easier to dial your car in to varying track conditions. Worth it?Depends on your goals versus your budget. We run the triples when we have the budget. They are a little better responding & performing (5.5ms vs 6.0ms) but is that worth more than double?Not unless every lit bit of performance is valuable to you. That last little gain of grip is small, but its expensive.
