We run a 3000lb metric on a 3/8 semibanked track and my question is we currently have a 200 on the lr and a 175 on the rr.If we change to a lr-225 and rr-200 what can we expect from the car.We have not run this car in about 2 months and the last time it ran it was really loose in and thru the center.Front springs are lf-900 rf-1000 with no sway bar.We have a 1100 that we were thinking of trying on the rf.Any help would be appreciated.

What do you run for stagger and wheel offsets on the car what size tires and what are your ride heights of the car

That was the same setup we used and worked pretty good all year

I would run the 1100 right front.

We run
1000/1200
225/200
If you want a ton of forward bite put a 225/175 and the car will be bad fast on the gas.

We run about 1 inch of stagger and 2 inch offsets.We are running a 88 inch roll Hoosier e mod tire,as for the ride heights i'm not sure because up until i have been reading this board it's one thing that we never check.

That is the same set up I have except I have a 1050 on rf. I measure my height at bottom front of frame just after the bend. On the back I measure just in front of the frame kick up on bottom of frame. Height on lf should be no lower than 7 inches with you in car.

lf---7
lr---71/2
rr---8
rf---71/2

Metrics work best with those heights, at least with me. I need more rear bite, I might try that 175 spring I have.

I have a question: The rubber spacer that goes between the front spring coils, does that add to the spring rate or keeps the rf from rolling less..

I believe that the spring rubber is supposed to just stiffen the spring.

I wold set your ride heights pretty close to what manseif sayed but i would raise them a little 7 inches is pretty low on the left front we found that it bottoms the shock out so we raies it a 1/2 inch we run
7 1/2 lf
8 rf
9rr
8 lr
gives you a inch of tilt in the rear and a inch of rake

Also put a 4inch or the rr adn a 3 on the left rear and see what happens to your car you could also put 3 inch offset across the fronts if you wanted to experiment

Miss Iowa, that sounds like a good idea on those ride heights, I thought the door window and drivers suit was shrinking untill I looked in the mirrow last week. My wife said I was starting to OINK. Did I say that?

Here's a stupid question how do i adjust the ride height.We are not allowed adjusters or anything above or below the spring.We use 11 front springs and 12 rears now.

You cut the springs and do it a inch or so at a time if you tkae more then that off you will end up buying new springs just a little cut will make a big difference

If you have never cut them before I would first tkae about 1/4 of the ring off and make sure that you cut the end that goes into the bottom a frame

This is the first year the we have ever cut our rear springs to get what we wanted for ride heights

Hey Speedway we use waterpump pulleys with the centers cut out to achieve ride heights and they are leagal if you tach weld them to the spring.

what size tire do you run with those ride heights because that will make a differnts from the frame to the ground.
