dry slick

[75t]

just wondering what would be the best ajustments to get the power to the ground on a dry slick track should we put more tilt in it or keep ajusting the four link. last night we indexed the top and and lowered the bottom bar and still not enough grip any ideas. thanks

You'll get more responses if you provide some more info like car make, year, bar angles, percentages, spring rates, track type, etc..... my 2 cents.

The biggest thing about a slick track is that your flaws in your setup will show up. An unbalanced car will kill one of the tires. A loose car will be looser. A tight car will shove the nose worse. There is no one magical adjustment to go fast on the slick. You need a balanced car and a smooth driver.

I am glad none of our tracks get that slick. I am neither balanced or smooth lol.

Go and give it a try at Needmore. :)

Needmore is a good place to get rid of your car if you can't sell it! Wreck-fest, one lane, dust bowl, tire eating, rubbered up hole in the earth.!

Bury right front if your track is smooth enough. We do it even if it isnt. Move j bar to below pinion. Or leave it up on frame and keep it level with pinion. Move rear end to the left 1/4 to 1/2 by adjusting j bar length. Keep your bars in the arangement where u c the most forward bite when it has a little moisture. If it feels good with a little moisture and its going dry slick for the main put one round in rf and 2 in lr. Adjust rf shock to tie it down less rebound. If u can drive it on 3 wheels u may be ok if all that is a little to radical. If u dont have a balanced set up start by working your rf and get your car loose enough where u can drive it with the front end then work to the the rear. Good base frame heights amost. Dont know about what type of motor or banking you are running and your driving syle. Our is a get to the corner and push it through the floor type. No smoothie here .the first to crack at the corner is go loose a spot

also leave the house with 50 lbs of bite with the driver in the car. i would start with my rearend square in the car.

So less bite is better for slick?

I have 2006 blue Rocket, 550LF 375Rf 200LR 250RR 130lbs bite

not really it depends on how your car responds. learned alot from crate racing and being on the ragged edge of loose. it really helps when u go back to horse power. i would work to balance your car then start tweaking. what do u look like on scales with your driver in. how much does he weigh

From my experience a lot of left hurts on a slick track. We ran on a track that was about like a baseball diamond clay by the end of the night. We would loose about 1% left and raise that weight from low left to the top of the center bar on the car, we would then drop the LR bottom bar 1-2 holes on the chassis and run it. We were in the 52.5-53% left when the weight was moved. We used that to win on that track running a crate against limited and supers, It also worked at Volusia Speedway when it got slick and slowed down.

I run in an all seel class and need to weigh 2400lbs. I have no lead on car and weigh 2405. I have moved the battery to the right and high where the oil tank goes on a super. I do that LR bottom bar deal every night. Up for hot lap and Heat, then lower it 2 holes for feature. My rocket has holes to move shock inward 2 inches on RR. I have been told to try that? Makes the car think it has less left? But stiffen spring?

that actually softens the RR spring, and lets the car roll over easier.

I was wondering, If I move it in should I stiffen spring?

[charcoal01]

If you went from like 15 to 20 degrees in you'd probably need to stiffen 25 lbs.

[DIRT69]

what happens when you move the rr spring in at the top and bottom, the angle dont change i run a 225 rr spring and i moved it in last weekend but didnt getr to run long enough to see what it was going to do. the book says to do that with a 250.?

If I remember correctly, Rocket starting doing that so you could stiffen the spring 25#, keep the wheel rate the same, but loose some of the effect of the rod pressure in a gas shock. This was to help when gas shocks were relatively new on the scene and you couldn't go low with the gas pressure.

Exactly, you must be keep'in up with the Richards! lol

So are me and Dirt 69 wasting time. I moved mine in at top and bottom and stiffened 25#?

53% rear ain't gonna get the power down well in a superlate on a slick track, unless its a truelly a momentum track or you have a 12" wing.... and you'd still be lacking.

[MasterSbilt_Racer]

Not necessarily. That is a way to promote roll and give the car some more lateral grip.

[N2Racin]

Wow, that did not work for me. Moving that spring in and only going up 25# made it loose. Going to move it back out. Had a 250 RR with it out. Went up to a 275 and moved it in.

[racin29]

try it with out goin up in spring if your loose on gas then that is because of the stiff spring

Loose getting in off gas, Way bad loose.

You may have to take out some roll steer too in combination; it's gonna roll over more/easier with spring angled in, so you'll be into roll steer quicker which will loosen it.

[MasterSbilt_Racer]

I misread your post. I thought you angled it, not moved both top and bottom.

[ROCKET11]

Try 550lf 375rf, stack 200/400 lr 225rr with 90 pounds bite w/o driver in car 52.5 to 53.5 left side, 54.5 to 55.0 rear

[fox1162002]

I know in the slick you need a good balanced car. On a small 1/4 track on my Rocket I sometimes run a 600lb LF spring if we start near the front also add a little more drop from 13 1/4 to 13 1/2. Its a little erratic but being up front you got more track to use. I have also put like a plain 3 or 4 on the LRF seems to slow the birdcage enough to tighten up the car. The biggest thing I've found out is always try little stuff in the final hot laps if you unload with a good car.

[Graff Spee]

Learn how to tune with tire temps! When its dry slick you have to think a bit more inline with a asphalt type set up.
