Car gets up on the bar (short 3-link) and when you go down in the corner and let outta the gas .....it gets a tick tight for a second and then snaps loose into a lil drift but if I kept it on the bar , it was badfast . I don't know if it has too much rear steer or needs like a 2080 lt. rr. shock or what will calm this thing down . I'm not sure if I can get use to drivin this sucker like this or if there's a way to keep it up on the bar more ? I'm basically dumpin this thing and causing this because i'm not use to being jacked up . It was a real slick stop and go track . I'd rather do something other than learning how to drive totally different if possible ?? Thanks

On my car I have found that when I let off the throtle going in the rear would unsteer and I was actualy entering too streight then I would try all kinds of stuff such as more throtle ,lots of rear break or throwing it in ...all of these attemts coused slow corner speeds and poor exits ranging from loose to tight off.......let me say this first....I checked tire temps and presures ,shock travle etc....and It all was good....I was running 3 1/2" stager and I was considering more to help the car roll throgh the entry of the turn better .....but my temps and preasures were telling me I had good even weight across the back .......the solution was simple ,I have always ran my rear square but I sumised the car was going down the shoot nice and streight and it would not hurt to add some static rear stear.....I trailed my right rear about 1/2 inch .....this made my car go from a real pain to turn to ....hammer down just before the apex all the way down the shoot,let out of the throttle and the car just sets and rols throgh the first part of the turn......got to go.....try it it may help you.

Hey , are you workin the brake and throttle at the same time thru the turn and keepin it on the bars or lettin the car settle down real easy somehow ? When I would run in real deep and dump the throttle ...it would do what I said in the first post but if I would just go in on the bars and keep in the gas just a lil ....it would drive on around real pretty and walk the dog off . It was all new to me so I couldn't keep doin the same thing every lap ....I would slip back into my old style . Now the car was jacked up 2 nites in a row a few weeks ago but I was haulin in the turns harder and just different style racetracks that being jacked up was not a problem , but this lil track was totally slick and different to drive on . I've got alot of rear steer and don't think that's the problem ......i'm thinkin more the driver is gonna have to adjust somehow or will the shock deal work real good for me ? Any other suggestions ........ i'm like you on shock travel , tire temps , etc. .......all points good and right on . Thanks

Yes I do work the brake an throttle at the same time , I like a hight cross percentage and depending on track conditions you can enter the turn tghter if you stay on the gas and us the brake to keep a tight entry....or let off the gas completely and use verry little brake to go in looser and come off tighter .......when you are in the middle of a raqce and you are wishing you had more bite off it realy ***** so this is why I like to run a tad more bite than I need ......get those feet working togeather and you will start loving this set up!......just curiouse ,how much angle are you running in your left bar....I have found 16 * to be perfect I ran 20 for a while and I felt like I was always chasing my tail down the shoot.......dont be afraid to go way high on cross weight , most base line set ups are pretty conservitive and I feel are meant to get a guy mid pack fast and comfortable.....good luck.

I've got a 3040 on the lt. rr. right now and about 16 degrees in lt. bar 15" c to c on both sides 8 degrees in rt.rr. . I've got 130 lbs. lt. rr. bite and like 53.7 cross 53.9 lt. side with me in car full of fuel ...... you runnin more lt. rr. bite ? I think this is mainly a driver adaptation issue .....car goes in a lil off straight and I would let outta the gas thinkin it would spin out but when I stayed in the throttle ....it just drove on around real pretty . I had 200 lt. rr. 175 rt. rr. when I got there but went to 225 lt. 200 rt. and car got better side bite and didn't drift much when I dumped the car but I was still messin it all up . I thought about double shockin the lt. rr. but rules don't allow and think maybe the stiffer compression shock will help me adapt too ? Any other suggestions ? Thanks

Each car is diferent ,I was having problems with my car rolling over and staying overon the right ,I think mostly from lead placement being high in my chassis ,so I tried something kind of unconventional and put a 3-5 valve shock in the left rear ,the car works great now .....shocks are nothing more than a timing device and once your close on set up they are the key ......sounds like you are close.

what you said was unconventional is actually what a lot of guys in my area are doing. I tried it and really like the 3-5 valve shock on the left rear. It seems to make the car drive way better off the corneron my car it also fixed the throttle tight problem.

to calm the car down when getting out of the thottle, AFCO makes a new valve shock 140-10 it will replace 90-10. the 140-10 does not allow it to drop off the bars as fast

Hey , is this a laydown shock for the rearend or a 9" for the lt. rr. ? If it is a laydown shock , it would prolly tighten the car up gettin in too .....wouldn't it ? Anyone using this and tell their experience ? Thanks

yes it is a lay down shock we are running it right now on our lightning it did tighten us up a tad bit but it really made the car driveable though the turns because it did not allow the car to slam down off the bars you can get this shock at lightning chassis 606-878-7223 it is a little pricey at 130.00 but i think it was worth it

what kind of angle are you using in the pull bar.
