had lots of people checking my h4 out tonight. I won the sportsman vta class. Should have ran with the big boys though cause my lap times were right on par with theirs for once. I was usually .5 slow with my old car. Loving this car more every day. And no broken parts since I installed the front bumper like rcwck suggested.

Well after a rubbish daya racing can confirm the new dcjs take a battering. Tbh the whole car took a beating but nothing broke until the last final where i had a crash that took out a c hub and hub but it would have broken any car

Can you guys take a picture of where you are measuring your droop from as when i was trying to set mine to 5.5 frnt 5 rear (car on a setup board measured under the hub) it affected the ride height

Put your car on that set up board and lift it in the center at the rear with something that is sharp/thin under the chassis. The distance you lift up the chassis at the point when the rear tires just break the surface is the rear droop. Both tires must lift off together. Do the same up front. Check front and back a couple times. It's lots easier and better to do it with set up wheels than your rubber tires.

I like 6mm rear and 5mm front. Droop is one of the tuning options that actually makes a difference.

If the droop is set correctly it has nothing to do with ride height. Turn out the droop screws and set ride height at 4-5mm with shock spring preload. Then set droop.

You should be measuring the droop to the edge of the suspension arm directly under the hinge pin. That should be equivalent to the 5/6-ish mm measurements you'll see on other cars and shouldn't restrict ride height.

Don't measure the droop at the bottom of the steering knuckle, that hangs a lot lower on the Hobao than on other cars and will definitely mess up your ride height.

Measuring droop by lift is valid but 5/6 mm is a lot, most people would go for 2mm front lift and 3mm rear lift. I prefer not to use that measurement as I find it less precise however it is a good visual check to make sure the suspension is set sensibly.

If the arms look to be more or less horizontal at full droop on the rear and just above horizontal on full droop at the front you're in the right region.

Under the outer hinge pin is where i have been measuring. On the front you can measure under the hinge pin just inside where the c hub is

Default droop

I actually use aluminum set up wheels when accurately measuring droop. I use a ride height gauge(not the stepped type) under each wheel for the measurement. Using the chassis blocks I have I need a 1/4" plywood shim under the gauge when I make the droop adjustment to be accurate. There is no guess work where to make the droop measurement on the car and is very consistant.

All my chubs, plastic and aluminum have 4 degrees castor. I believe that's why they are marked L and R.

You better check and see if they are oriented correctly. I have seen them installed backwards many times.
