After doing a search on ride heights I set mine to LF 7" RF 7 1/2 LR 7 1/2 & RR 8". The question is why? As far as playing with set ups I'm a rookie but from what I can tell this is the site to learn about it. If you were teaching someone about ride heights how would you explain it as far as why is the RR set at 8" or RF at 7 1/2" ect. can someone please explain in plain english? Where would ride heights rank as far as setups are concerned (Was that a loaded question?)I.E. winning and loosing.. Thanks for all the info.

Ran these heights first time this weekend went from 12th to 4th(very dry slick) so it must mean somthing, or I just got lucky but with all the post its hard to say LOL....

Ride heights are important for several factors.Ride heights are affected by tire size,spring length and set up.Naturally the right side needs to be higher on the right.as we go to the left.Ride heights also are different according to the chassis used.I race a metric but we are allowed drop spindles(s-10 lowering).So my ride heights would be far different than yours.We tryed at first to set up a metric like a older chevelle type car.Did not work.Has the car been on the scales?If it has take GOOD ride heights measurements at the same place everytime.where the frame is welded to the "stub"on a metric is a good place.If you was to scale the car and set the ride heights,then was to change a spring just measure them before and put back after change then the only change made is the spring not the rest of the set up.So depending on what context you are refering to when the ? is raised why are they important.

Trynmods, what are your spring rates and heights?

Metric car with stock suspention. Spring are LF 900 RR 1000 both 9 1/2 w/spacer LR 250 RR 200 both 11in.w/spacers to get heights. Car is still pretty loose coming off corners, D.O.T. radials zero stagger in rear 1 1/2 front I may even try less in front. How would putting a 1in. spacer in rf help coming out of turn. I have a 3in. off on rf now and a 2in. on lr.
So with all that I still think in high in heights any suggestions? Thanks

Put the one inch spacer on the left rear. It will not affect the ride height much, due to the static wheel weight being over three times the rate of the spring. Tour ride heights look good and this should increase your static cross weight, which should increase your forward bite.
The one inch spacer in the RF, (spring rate heavier than static wheel weight) will greatly affect your ride height and dramaticly affect crossweight. You will probably wind up with a push if you choose to install it there.
Good Luck!

The reason for checking ride heights is mostly to keep control of your weights at each wheel. If you change to a different size tire idealy you would want to add or subtract height from that corner to return to the ride height you started with. Otherwise it effects more than just stagger. As far as finding the right starting point, I have always adjusted the ride at thr right front to get the lower control arm level to the ground. This should promote camber gain as the tire goes into bump. From there I set the left front about an inch lower. Rear heights I adjust depending on how much roll steer I want to build into the car. Usually the left rear would be about the same as the right front. Then I would adjust the right rear to get the desired wedge. Occasionally I've had to raise the left rear a little more to get the right wedge. Hope this hepled a little.

How heavy is your car? It seems like your left rear spring is a little too high. I would think a 225 would be better. Also your right front could be stiffer too get more forward bite. Is this a hobby stock?

The car weight is 3350. Went to a new track last night 1/4 mile med. banking, the car was really bouncing in the heat I changed the rear springs to LR 275 RR 225 it seemed to help and the car felt like it had more bite coming off the turn does that seem right? Also with my heights the way they are in the front what would the affect be if I took the spacers out of the rear and just ran the rear on the 11in. springs?? Thanks for letting me ask all these questions, they may seem crazy but I'll never know unless I ask or try it.
