Pro 10: 235mm Le Mans Prototype Pan Car Discussion

thought i'd post my setup for interests sake:
surface: medium traction asphalt. bumpy
chassis: 235mm crc gen x 10 le
body: protofom p905b. side dams and 15mm gurney flap
front tyres: jaco purple. 58mm. no additive
rear tyres: xceed asphalt 25 shore. 62mm (straight from box). generous lathering of sunscreen for 15 mins
front camber: -2 degrees
maximum caster (all 3 washers to rear)
reactive caster: 5 degrees
front spring: white. 2 mm droop or thereabouts
short wheelbase. 220mm front track, 230mm rear track
centre spring: crc blue. no droop
centre shock oil: ae 20wt
side spring: crc blue. tweak screw 1/2 turn past touching chassis
8mm front ride height, 7mm rear
5800mah 2s lipo. 6.5t novak ballistic. 18/75 48p gearing
car was very stable, fairly easy to apply power out of corners. lacked high speed steering. will try softer front tyres and/or additive next time. could handle more power. if i can find a bit more mid corner steering through the sweepers car will be very quick i feel. incredible fun to drive

If you have the peugeot 905B high downforce body, remove the gurney. It produces too much downforce and understeer at speed.

Thanks, I had thought of that too but was reluctant to do away with that nice 'glued to the track' feeling around the sweepers. Will try it though.
Btw, have you tried many different bodies? Would you recommend another one to achieve slightly more steering?

If that doesn't add enough steering, try a firmer center spring. That's a fairly mild change. Heavier oil will also make a difference. Stiffer side springs make a bigger change, what ever you change, go one step at a time. The easiest thing to try would be a bit of additive on the fronts. Start with 1/4TH on the inside, then go to 1/3RD or even 1/2. Makes a big difference and it's easy and you already have the stuff. I haven't raced asphalt in years, but your set up is kind of soft for what I remember.

Indeed the setup does look on the soft side.
Depending on the type of track and available traction i either use the Peugeot MD for 1/8 tracks. Peuegot HD or the Andy Sauber Mercedes for smaller 1/10 electric tracks.
I drive in the 10.5t class though so High downforce bodies like the Peugeot HD creat drag on 1/8 scale straits and can result in a hotter motor and/or lower top speeds. Hence the medium downforce body.
You can also buy a lola, stiffen up the chassis and tires and be done with it. A lola is easier to drive with a mod motor and it will stick the car to the asphalt like glue. Be prepared for massive drag though

the other main problem i'm having is that i don't seem to have enough space in the rear pod to gear the car low enough to run as fast a motor as i would like. will try a motor fan and have another look at the pod to see what i can come up with

I use a hobbwing 120A v2.1 with a hobbywing xerun 10.5t motor.
Big 1/8 tracks or small electric track, i always use roughly 36mm and set my dynamic timing for straightline speed and acceleration in/out of the curves. Worked out pretty good so far. Last race on a tenniscourt size track i only needed to change my settings twice and motor temperature was roughly 63 degrees C after 7 minutes race. I love dynamic timing esc.

I race with the Hobbywing also and I can only say that it rocks!!! It is cheap, easy to use & set-up and overall very easy to work with plus it is very smooth and powerful...
