I run on a med-hi bite track.

Also, I've heard not to put them in the pivot blocks because they bend quite easily, is this true?
the grey grease will work fine... I've bent several screws already on the Pivot blocks... you can try them there and see what happens...

Clint, I have tried Thad's, Hara's and both of Kevin Kane's setups. Unless your track has nats style grip I would not suggest Thad's or Hara's. Go with Kevin Kane's setup. Now his first setup is more for a standard club race type bite which is what I have been racing on. The car carries tremendous amounts of corner speed and has great on-power steering. When I tried his second setup which he posted mid to late last month the rear of the car felt loose and I lost too much mid corner bite in the rear. I feel this setup would be better at a large turnout club race or at an established track that has great bite but not ludricous nats type bite. I hope this helps.

I also prefer the Parma Alfa body on carpet. It has great balance and transitions very fast.

Thanks, I will look for Kevin's first setup as we have an established track but not insane grip. plus, I am looking for more of a base setup to work from...

Clint, here is the second setup that is more for a higher bite situation. Kevin, I and some of the guys I race with are running the PRP HTS chassis which is a 3mm upper and lower chassis plate but the other guys that I race with that have the stock plates are just adding .5mm to the pivot blocks and to the inner camber link ball studs to obtain the same suspension geometry and doing that works real well. Hope this helps. If you have any questions just hollar. You might also go to the Team PRP thread for more setup tips.


Here is the setup that I was running so everyone with a HTS chassis can try it out and see how they like it.....

Front....
6 deg castor blocks
1 deg camber
inside hole for camber location
2mm under inside camber ball stud
1 hole in from all the way out on the shock tower
45wt oil
#3 piston
Hpi pink spring #6759 30.2 LBS
Outside hole on lower arm
Forward hole on steering knuckle or Losi hub Mod.
#1 akerman location
0 deg arm mount block with 1.5mm spacing under it
2mm spacing under front rear arm mount....gives the car kick down
1.5mm droop over ride height
5mm ride height
Black sway bar with 2.8mm showing

Rear
1.5deg camber
inside hole for camber location
1mm under inside camber ball stud
inside hole on hub
Shocks in the outside hole on the tower
shocks in the middle hole on the lower arm
40wt oil
#3 piston
HPI red spring #6754 24.2LBS
Rear arm spaced with 3mm in front of the arm and 1mm behind the rear of the arm.
Rear hub spaced with thin shim in front of the hub and thicker shim at the rear of the hub(kit stock spacing)
2 deg arm mount
1mm shim under front arm mount...gives a little anti-squat
5mm ride height
2mm droop over ride height
Silver sway bar with 1.5mm showing

Body Losi Alfa
Motor KT Hobbies EPIC Roar Stock aka Kraig Tuned Limited Ed.
Geared 34/104
Tires TM racing Plaid2 fronts and Magenta Rears
Tire Size 2.26 dia

Edit....I was also using 2 center post one in the front and one in the rear with the middle spot open.

Nothing wrong with that. Just add .5mm to get the same settings as these setups call for and you will be fine. Glad you went PURPLE!!!

Maybe someday we will get down that way for a race. I think you guys are like 6 hours away.

It was just by chance that I was able to get the Pro4..

Some Oklahoma racers are supposed to coming down this week for some racing... too bad I can't race, but I will practice at least..
