Adding more droop will more likely give you understeer so you will just go slower (too much load on outside tyres). If your running kit springs then chances are that is your problem. I would also look at your oil weights. Are you running split weights or the same oil f/r?

Adding more screws to the top deck is going to give the car less chassis flex - making the rear even stiffer. Some argue that using chassis flex is less effective then trying to set-up the suspension for the conditions, however, utilizing chassis flex in addition to a well-set-up suspension makes the car easier to drive.

In my first testing session, where I was running the car on a medium grip outdoor track (prepared parking lot - with sugar water), the S411 tends to like a little less droop versus some of the other cars I have ran. I've also went up in oil, again making the car very stable in high speed corners. Depending on the track you are racing at, you might want to go harder with the suspension (i.e thicker oil) to calm the back-end down.

What diff fluid are you running?

Mwoods -> I ran the S411 on 3 different tracks now. Two in Toronto, Asphalt Home Depot Parking lot tracks with sugar water med traction and now tried it in Village Raceway track down in Royal Palm FL. Smooth concrete track with med+ traction.

My car did the same as yours with loose on-power coming out of corners. I tried droop first, but it didn't help much. Best change for me was two things:
1- Extended Rear wheelbase to use 5mm spacers on the front suspension block on the rear.

2-Use heavier springs up front. Use 16 LBS (Serpent Yellow) for med traction asphalt and now 19LBS (Serpent kit Orange) down in Village Raceway.

My droop has also been lowered to the 4mm mark. But that's up to you to fine tune after you sort out the wheel base and springs.

Wheelbase was where I saw the largest change from kit settings. I improved my 1sec lap times on the Toronto tracks just with that alone.

one thing i think it mite be is the rear droop screws dont hit the chassis wen its on the ground , wat over all lenth u building ur shocks at

thanks

If you are running a kit diff then try 3000cst in your diff. When you change to 4 bevel gears the diff works a lot better on power so with 4 bevels I us 500cst oil and it is better again everywhere on the track.
