174 Draco Springs What’s the Big Deal with Draco Springs? There are many grades of spring steel, just like there are several grades of steel used in sway bars. The concept is the same in both. The better the steel alloy, the quicker the spring or sway bar responds. The common grades are in these spring steel families: 2000 series – Cheapest, low grade, OEMs use 4000 series – Much better grade / twice the cost 5000 series – Better than 4000 series & more expensive 9000 series – The Ultimate Spring Steel / Very Expensive Since there is NO SUCH THING as flat asphalt … it all has small undulations and our suspension needs to respond as much as 5 times in a tenth of a second (at only 68 mph) … to keep the tires following the asphalt … to have grip. Otherwise, if the suspension doesn’t follow the undulations … when cornering … the side G-forces push one end of the car off track as soon as the tires lose grip. Hypercoil was the innovator in the 90’s, being the first to use 4000 series spring steel on Indy Cars. I still use Hypercoil springs in my less hardcore applications. Most “brand name” spring companies use 4000 series spring steel today. Japenese company Swift utilizes 5000 series steel. Good stuff. Only Renton Springs & Draco Springs make car springs out of 9000 series steel at this point. Renton doesn’t cater to our market. Primarily NASCAR, Indy & IMSA. Draco makes 9000 series coil over springs in a wide range of heights & rates for our 2.5” ID coils overs. And they offer them at an amazing price relative to 4000 series springs in the market. We offer Hypercoils as our base springs and they run $75 each. The Dracos are $99.99 each up to 12” tall, any rate. So a set of four is only $100 more. That is a lot of track performance & peace of mind for the buck. How are they better? No sag. Not less sag. None. Nadda. No deformation. None. Nadda. Not Gonna Happen. No rate loss. Same rate today as in several seasons of racing. Quicker responding suspension = MORE GRIP Quicker reacting supsenion, coming out of a corner or through chicanes = Quicker Lap Times The only springs that will live through the abuse my race teams put them through are made of 9000 series spring steel. We ran the Draco springs. I can't tell you how long they'll last, because we never had one fail. They cost us more, but lasted basically forever and always performed consistently. Draco offers a full line of 2.5" ID coil-over springs in lengths from 8" to 14" & rates from 100# to 800#+. For years, Draco springs have been one of my little speed secrets to building better handling, quicker race cars. When you see purple springs on a car ... those are Dracos. Purple is bad ass !
