Thanks for the tip. Actually I may have solved the problem my self. When I assmebled the car I didnt install the springs between the pads, as I have always done on any other cars that had this feature. I just never really subscribed to the reasoning for using these springs so I have always left them out with no negative results. While I had the car apart, I studied the the brake assembly a little bit and noticed the brake cam does not activate the pads in the center of the pad but is offset maybe 3-4mm. Operating the pads and watching the disk engagement it looked like some self engagement might be occuring that possibly the springs might eliminate. Ran the car with the springs installed at the last race and the brakes seemed to be better. The track I was at is a pretty flowing track with not alot of braking required. My next race is at a real "stomp and stab" type track so I will see how it works there.

Just as it sounds

Bumper on
15 is a ok starting point the gap between the front of tr bumper and the front lip

Depending on if you need more steering or less you change that gap

This effects high speed steering the most

I think the range is 13-21

I bought my c801 used and it has a serpent bumper on it so I'm not sure if that bumper sticks out farther than the stock bumper. Can you cove me a number from the front of the chassis plate, or should I just measure 15mm from the serpent bumper? Thanks.

Sorry for the delay

Ok so from my front bumper to the lip of my body my car is setup 14.5mm

Using the center screw, place one blade of the caliper in the screw head, I used the small caliper blade(the one used for checking the inside Dia)

So with the small caliper blade in the screw head to the front of my body I get 62.5mm

This is with a P909

The 909 has a little more steering

The R18 is good just smoother on higher grip.

I like the 909.

With that said I have some PFL128 bodies to try

And my Teammate really liked the R18

Now as a guess a 909 mounted more rear might get close to the feel of a R18 more forward.

A body I did not like is the R15 pushy lose

Also I would like to add that the bumper can change the cars steering at higher speeds a
serpent bumper may change your cars steering vs a Capricorn bumper, I use the newer Capricorn
bumper, its softer and less prone to breaking Desoto has the new ones all the old ones went out
last year

Hey Guys,

Sorry for the reply with my 1/8 scale set-up, just been really busy. Some racers have been asking me so here it is. My car was actually really good, but the results to not show that. I has a car with good steering and was able to keep good speed in the corners. My fast lap in quals where 14.7-14.8, not sure at the moment. My issues was having to pit or we could have competed for the TQ. If I missed anything on the set up or it is confusing just ask.

What I did that is not on the sheet.

-ran the front with flex radio tray.
-ran the rear with flex as well
-ran the front upper arms with no shims under
-I used the new bar in the front with the stiffer one (I think it is 1.4)

Thanks,

DJ Apolaro

thanks a lot dj, is the tire size you wrote on the setup sheet what you set up your car to, ie ride height? do you recheck your ride height when the tires are lower and then adjust it or you set it to 67.5/ 47 and just drive it until the tires are lower than what you desire? thanks

Is the flex system, top deck and the one near the motor, a significant difference? Is the gains worth the $$$$?

I would say the one near the motor yes if you run the rear screws loose you can get the idea, but its better with the correct parts.


if you wanted to wait you could cut the upper deck Like the new kit, seen in the picture a few post back.

No going back after you cut it though, not as much flex as the "flex front" but more then the stock piece
