I run a Monte stock 4-bar and I am extremely loose. My rear shocks last nite only had 1-1 1/2 inch travel. My rear % is only 48.3% and I'm wondering if that is my only problem or not. If I put 100# over rear axle it should raise my rear % to 53%. I'll be 200# overweight but if it would give me some bite who cares. I run 93's on rear and 6-2 and 5-3 on front but it still won't transfer weight to rear. PLEASE, I need help and ideas quick-racing again tonite. Thanks, Donavon.

Donavan did you fix that height on the left rear also if it is loose add say 50lbs in that left rear that will tighten you up. That and adding as much cross weight as you can. I know your rear tires are close in rollout but how close if its that loose and you cant add weight to the left or get more cross then put that reverse stagger you ask about last year it will tighten you up as a last result. See ya tonite save us a spot and lets get close to Tony he will try to park against the fence were we did last year. Also i am going to try this weight i added this week again so we will be up to 48.3 also. I am thinking of running supers also just so i have a feel for the car for my class. If i do and you are off the track and around i would love some help with gas and air after the main if you arenot at scales. I think you told me last year that they were only like 3/4 of a inch between the left and rear tires that wouldnt hurt that much but i do relize that you have a beedlock on that side so not sure what you will do there unless you have another wheel.

I'm running straight up in rear-no stagger. I have RR tucked in as far as I can. RF is all the way out, so is LF. My front track is about 1/2 inch wider than rear track-that's all I can get. Rear springs are 200's. I don't know if I put my 225 in LR if that will help or not. Going to try and find some lead and mount 100# in rear. Motor is stout-serious stout. The car is really pretty good on entry and apex, just extremely loose on exit. I've scratched my head so much I'm going bald. Good luck tonite.

Ok well lets see what you have on lr move it out put a 2" off on lr. Also yes stiffer spring in left will help alot get out there and change that to that 225 and if you can put a spacer so you only have like a 1" difference in the rear as far as right heights. Really the rf and the left rear should be about the same height. I dont think you need all that 100 with it good in entry and appex just maybe add 50 and change spring. Dont do to much at once a be easirer with that right foot lol

I don't think I have a bent shock or bind, car bounces real smooth. I did change LR spring from a 200 to a 225(I don't have a 250 or I would have put it in) And you're probably right, my right foot was pretty heavy last night. Just put in new motor and was wanting to see what she had. I always have been loose but last night(first time out this year) it really was a handful. I might have messed up rear upper bars since I raised the mount on the frame trying to get some upward angle to them. My lower bars are right at level.

my problem with the shocks was the left rear was mounted to low keeping rearend from dropping,not enought stroke, so i moved shock mount up for more tavel..

on your car you want top links running down to the frame, and bottoms running up to frame the left even and the right running up. my car once set up like that drove staight in the turns. slung rear out about a foot and you could stand on it and it would come out of turns perfect.. best car i ever ran and ended up selling it...

How do you guys change the angles of the arms? Are you doing it by drilling new holes in the arms thus making them longer or shorter?

Level the car with stands under the suspension and use an angle finder. You can find them at LOWES or most other home or tractor stores. It sounds like you may be a little light in the rear. It seems like when you increase rear percentage you can also come up on cross without sacrificing corner speed. Hope this helps, just another guys opinion. Also check around on the net on METRIC 4 LINK you may be suprised what you find.
