what is the best upgrade for a hyper 7(dont say engine, i got a picco .27 ready to put in it). My buggy is completely stock exept the servos.

5 cell hump pack

Shock oil/springs to fit your track and driving style, diff oil setup to fit your track and driving style, universal or CVD drive shafts, clutch shoes, clutch springs, clutch bell, and a radio (if your using the stock ofna radio... if you are upgrade the radio first).

can anyone set me up with a shock set-up.

Engine:hyper .21 8 port with Collari .30 carb. (sick)
driving style: drive it like i want to kill it. Or in other words, i do what ever i can with it.
track: lots of jumps, mobles(little bumbs), sharp turns, one long straghtaway.


Thanks. Any help will be highly appreciated. I am going to the lhs tomorrow(March 5).

With a bumpy track you should be using a light shock oil. Sense the hyper 7 piston holes are pretty small I'd start with 40f-35r or even 35-30. Also use medium springs.

The bumpier the track the softer your oil and springs need to be to help that tire mold to the track surface easily. If you have a heavy weight oil you'll just bounce because the suspension doesn't soak up the bumps like it should.

The smoother the track the thicker the oil and springs should be. This really makes the buggy feel more stable and consistant but if you hit a bump it will screw you up pretty bad. A lighter oil will make the cornering feel kinda sloppy on a smooth track.

right now i have blue springs and a 40-35 set-up. It sits on the ground, no suspension travel. This buggy pro recomended this. Whats wrong? what holes on the shock tower do i use?

Sounds like you don't have your spring pre-load adjusted properly. Fill your car with about a half tank of fuel (to get an average weight between full and empty), pick it up, and drop it from about a foot or so onto a flat surface. Slightly push down on the top of the car (maybe a half inch or so) a couple times to get an idea of your car's ride height. You want it to settle with the suspension arms parallel to the ground, or "arms level" as some people say. If your car is lower than this, slide the collars on the shocks down (toward the bottom of the shock) to increase pre-load, and this will raise the ride height at that end of the car. If you have to lower the pre-load collars so much that the spring bottoms out on itself before you reach full compression of the suspension, then you need stiffer springs.

One important note, despite what many think, spring pre-load adjustments do not increase how stiff your suspension is. It just increases the initial tension on the spring, which changes ride height.

First I'd check the ride hight set screws in the suspension arms. If you look down at the suspension arms very close to the diff case you'll see a little set screw in there. If you screw that in it will limit how far your suspension will come up. Its a simple check that only takes a second so I'd do it first and then start messing with your preload like KX sujested.

I always try to offer the easiest advice first. In this case Super Dave came up with an easier one. Check the travel limiting screws he mentioned first before adjusting your spring pre-load.

Defiantly for a metal geared servo for your steering.
