Please post how your suspension is setup for running the 1/4 mile. I have t-bars dropped, caltracs, and overloads pulled. I am getting alot of wheel hop, particularly in the rear. thanks

Chassis setup for racing.
- Thread starter bigbird

forward 4 link, no wheel hop but no traction either.
i need some slicks
big bird have you adjusted the bars at all?

Tires and wheels are important.
Sticky tires and front rims don't "stick out" will go a long way towards stopping hop.
Even with excellent suspension, steel radials will hop if there is partial traction at a poorly prepped track, or one with water on it.
IIRC, there is a thread about how I have Casper set up as far as suspension goes.

Bilstiens all 4 corners ,spring clamps 3 inch drop shackles in the rear lowered t bars almost all the way down. I never got any rear end hop the front end is another story sometimes when i swiched to my 20 inch rims and toyo proxies i strted cuting consitant 1.73 60fts prior to that 1.8-1.9 was avg for me with my other rims and tires.

Casper's drag suspension=
rear-
Single leaf + overload
Caltracs
M&H DOT drag tires
Drop shackle (DJM)
front-
SuperDiesel centerlink
SuperDiesel tierod sleeves
No swaybar
Drop keys
M&H DOT drag tires, high offset rims
This normally gets us 1.6's and has dipped into the high 1.5's. Most tracks we will spin the tires instead of hopping, most the spin is in second gear.

what pressure are you running your tires at? i have the same tires on my 22's and can't hook for $hit. i know it's bit different than your's but i should be able to do better than a 2.7 60'
T-bars lowered all the way, 3 turns on the right side.
Overloads clamped front and back.
30 psi front 25 psi back on 18's
bilsteins on all 4 corners
All that net's 1.7's

Since Pat brought up wheels and tires, mine are usually a set of worn 265 ATs on stock PYO wheels. They've been good for a best 60' time of 1.66 seconds. I've run the 285 MTs on H2s as well, and they've produced a best of, I think it was, 1.72 seconds.
nope 2wd and stock trans right now. yea i know 2wd and stock tranny is hurting me but i figure w/ slicks i can drop almost 8 tenths off the 60'. my trap speed is pretty good though, 98mph.
My set up:
Cognito supports and sleeves
T-Bars lowered all the way
stock shocks
tires 28 front 20 rear
305-55R20 Nitto Terra Grapplers
no clamps or traction bars at the rear.
Cut 1.7 60's with occasional wheel hop (See Video in sig. 1.75 60 ft on that run)

Good enough for 1.648 60's

Tires are toyo proxes, Shocks are Bilstein. I just picked up some rancho 9000's. Here is my video tell me what you guys think of the launch.

No I haven't, what do you suggest?
Full leaf pack, overloads clamped, stock 245's aired down to ~30 lbs, 3000lbs of dead weight sitting over rear axle.
Try it with the Ranchos installed set to 9 all around & see what happens.
From what Ive heard the Caltracs are meant for 2wd vehicles & are more for weight transfer to get traction, something you don't really want on a on a 4x4.
