need help with traction on 2013 gen x

[lost dog]

i am having a very hard time trying to get forward drive in this car when the track dries out when the track has a little drive the car is good not bad my coils are as follows LF 500 RF 375 RR 250 LR 200 AND I AM RUNNING 85 POUNDS LR LEFT IS 54% REAR IS 54 % CROSS IS 49 %
WHAT CAN I DO OR LOOK FOR

Possibly try raising your wedge we run around 150 pounds in our genx on a small dry slick track you don't have to go to the extreme but bump it up some and what is your 5th coil spring and how much preload is in it

[Matt49]

What adjustments are you making as the track slicks off? Shock adjustments? 4-bar adjustments? J-bar adjustments? A little of each?

HP,
Curious, did you add all LR on bite or spread the wealth (if you know what I mean)?

[Drop Shock]

Chain the right rear, and get the spring about half an inch from the nut

[racerkid12]

softer LR spring will induce hike but will give you less drive, possibly why some much wedge is needed

Not necessarily... It all depends on car attitude when you pick up the gas. Your thinking will likely only apply at the start of the race for an experienced driver.

Can someone please explain to me why the softer spring on the LR induces more hike, or faster hike.

When weight transfers laterally from left side to right side in the corner, the ride height will increase based on the wheel rate. If the lr loses 200# with a 200#/in wheel rate, the ride height will go up 1". If the wheel rate is 100#/in, the ride height increases 2".

Thanks MBR

Which increases LR thrust angle faster which is why a softer LR usually yields more LR drive than a stiff LR. It's contrary to the "heavy spring gets the weight" rule but is the correct way of thinking about it on any car with a LR spring behind or that "hikes" in the corners.

what if the lr is off the spring when on the chain limiter?

[latemodel21m]

I would just try using the lr shock in back of the rear, no shock in front of the rear. With only one shock mounted in the back of the rear provides a ton of traction when its dry slick. I run my mb all the time that way.

Then spring doesn't matter at that point.

I do not have a gen x, but was wondering if removing front shock would help for all 4 bar cars? Also my spring behind is not unloded when on the chain. im scaling at 80lbs with out front shock, than at 140 hooked up
