I would like to know if when a spring says it drops your car "X" inches, does it truly? I've read something that said it doesn't. Such as a 2" drop only acually dropping the car 1.8"'s. So, I want to know if springs live up to there claim? Are they exact or more of an approximation?

Thanks-Jason

 

dont count on it being exact. You should buy springs based on their ability to function not ride height.

 

There is no way for them to give you an exact number and it be 100% correct for all cars. I can think of 10+ different engines (h22,h23,b16,b16b,b18c5,b18c1,d16's, zc, d15, b18b, b20, ect)that could go into a civic hatch that all weigh different wich would affect ride height. Aircon thats like 50 pounds. And other trims that vary from car to car.

So to sum it up the numbers they give you are approximate and I would expect them to be within 1/4"~1/8" of there number if the springs are made by a reputable brand and if your car is fairly stock..

 

they are pretty close, did you measure it from the center of your rims to the fender?

 

The reason i'm asking is, i'm looking at mocking the R*SR GT 2 Spec exhaust, w/ my own custom exhaust. Which runs straight down the middle and under the rear of the car. Eliminating almost all bends except one. The problem is it's a race application because of the potiential to damage the exhaust. Right now i have 7 1/2 inches of clearance. When I add the 2" drop springs and the fact that the piping is 2.25" this leaves only 3.25" +/- between the ground and the exhaust depending on how true the drop is. Being that my car is a daily driver,soon to be weekend road racer, I don't want to crush my exhaust but i would like to get the most out of the exhaust as possible.

I think you're going to find that the gains from such a setup will be extremely minimal/non-existant over a properly-designed system that basically follows the stock layout. I would suggest aiming your efforts at the header end of the exhaust system, and running a more traditional cat-back.

I completely agree with this guy^^ get a nice header, and even better, run the exhaust with either a dump tube off the header, (forget what they're called) or just header at the track to get the best times, torque will suffer, but you'll get a nice kick in the horsepower area and maybe only run a stocker 2" exhaust for around town, HP might suffer just a tiny bit,(5hp?) but it'll keep the fuzz off your back...thats if you run stock muffler of course
