Tech Question - GT500 KR Coils

Q - Mike,

I bought both front and rear springs for my KR from Eaton and I am not happy at all. Just look at the picture. The nose of my car is sticking way up in the air. This is crap. I was sent the wrong springs. What are you going to do about this? - Jerry

A -Jerry,

Supporting weight is one of the main functions of a spring and the engine and trans that I can see you have not installed yet will add at least 600 more pounds for the springs to support. I have a feeling once the engine and tranny are in the car will sit just fine. Let's not worry about how she sits until they are installed. Be sure to let me know. - Mike

Mike,

I thought you guys were a bunch of jerks and your answer boarded on being a smart ass. But I bit my tongue and put the engine and transmission in and the car began to sit much better. By the time I had the glass and interior all in my baby sat PERFECT !!! I am sorry for everything bad thing I said and thought about you. You guys sure know your stuff. I am letting everyone I know you are the ONLY place to get springs from. Love ya man!!! - Jerry

Jerry,

1st thing I did was show my wife your email because she never thinks I am right. Believe it or not, your impressions are shared by many. A very common mistake people make is not thinking about the missing weight of the engine, trans, glass, interior, etc.

Those missing components means less weight for the springs to support. The 1st thing they think is they have the wrong springs.

It is not only the missing weight but it is also the way the weight is distributed. Let's use your car for an example. The engine and trans are in the neighborhood of 600 Lbs. If you and several of your buddies who's combined weight equaled 600 or so Lbs. stood on the car, the car would still not sit right.

Why? Because of weight distribution. Your weight would not be in the same location or spread across the frame the same way the engine and tranny weight would be. We always say get the car 98% done and drive it, then we will talk about the way it sits.

And I mean drive it like you stole it. Do not baby it, hit the gas, stomp on the brakes, bounce it, jar it, work that suspension. Flex those springs, let 'em work. Then check the ride height.

I love not only you but everyone who enjoys old cars. - Mike
