RCFREAK-
Are you running a "lowered" front shock tower? If so, drill new holes up top for the camber links so the link will sit more parallel.

Also try to run some anti-dive up front. I ran ultra lows up front and stock roll center mounts in the back of the front arm at the snowbirds last year.

Where do you need steering? Off power, on power? Entry, mid or exit?

hey guys! hope anyone can help out... im doing my orders from Team Corally and would need some information about the RDX... what parts are breakable with the car that i would need to get hold of, also there are different types of wishbones, servo saver etc... the local track we have back here in the Philippines has a low-bite traction & quite bumpy... will the Kimbrough, Star Force fit the Gear Adaptor that the RDX have? many thanks hope to hear a reply from you guys soon..

Juan you are going down.

do you guys have enough steering in the car?? i find that on medium bite unless we have bigger race venues which we run 19turn. i still keep trying to find more turn in and steering throughout the turns.... motor wise.. when roll out is right the car has the same amount of speed.. but i can never find enough corner speed in the car.... pushes entering corner up to middle and decent exit steering... basically not enough steering. off throttle also!! i have to drive the car strapped to keep up with cars that carry more corner speed.

most aggressive ackerman
4 degree caster
front shocks in 1 hole
rears out
links short
regular roll center .. rear
ultra low ... front
30lbs in front
28lbs in rear
short wheelbase front and back
60 wt
40 wt

Ok..... few things I noticed about your setup, and a few things you don't let us know.

1) Is this foam or rubber?

2) most aggressive ackerman position, so you have a longer link? Great. Yet the ackerman setting you describe takes away the most amount of steering through the middle and exit of the turn (if the setting is different please correct me)

3) Your front shocks are in only one hole. That makes the shocks pretty vertical which will give you some sensitivity around center, but through the corner it will stiffen and push.

4) I've gone back and forth on this but shocks farther out on the rear will give more stability and plant the rear more through a corner. Others I have spoke with have recommended leaning them in compared to the front for more steering. I know, its odd, which even I debate. It's worth a shot though.

5) short links are great for transition but they take away traction. Longer links will add forward traction and keep the car flat through corners.

Questions I have......

What Droop (up travel) are you running)? Do you superglue tires? What ride height are you using? How much rear toe in? Any toe out in the front? What pistons?

I am not trying to say anything bad against you, just wanting a bit more setup info to help you with your ride. Let me know.

Jeff

sorry jeff. forgot to add the rest...

Foam tires
yeah longer ackerman links
i guess ill lay the shocks down a lot more
no superglue needed on our track.. medium bite carpet
ride height 5mm.. droop 1.5mm
standard piston
60 & 40 wt.
1 degree of rear toe
0 toe in front

thanks for the advise !!

gonna really try laying shocks down and changing camber link positions..also either go back to standard ackermanl or medium ackerman..

Yeah, those sound like good places to start. I think a lot of people get confused with "initial reaction" versus initial steering and throughout the corner. I even do it.

I would remove some droop. Try 1mm front and rear.

Standard pistons. Well, depends how old your kit is. Lately the standard pistons are 1.3mm which are quite large. You might try different oil if they are the 1.3mm pistons. Perhaps 10wt thicker front and rear.

You can thicken just the rear oil as well. Thick oil in the front acts like too stiff of front spring or too vertical of a shock angle. I dropped 10 wt on asphalt a while back and i was amazed. I even dropped 10wt more and thought WOW, what have i been missing. The lighter oil transitioned faster and carved better through the middle and exit of the turn. Double bonus.

If you want to gain back some sensitivity around center then add 1/2 to 1 deg of toe out. This will regain the touchiness you probably like. Also, drop the front ride heigh 1/2mm lower than the rear.

Hope this helps. If not call me at CorallyUSA.

Oh.... and to answer the Roll Call.......... Mod Foam and Rubber 99% of the time. Ran some 19T lately but it was pretty slow feeling.

Pretty much. The upper camber links pretty much become the "lower holes" and the links can stay pretty flat. Be sure to drill small pilot holes from the back side of all the countersunk holes. Do not countersink the new holes. Simpley use Round Head screws with the tower backwards which will help keep the tower stable.
