set ups
 

So what set ups do you guys run
Tyres, ride height, gearing etc

Having trouble with the back end just flicking out

Thanks

Hi rich

there's quite a good thread in general car talk, mardave v12 set up, found it earlier in week and replied to bring it to the front :thumbsup:

Thanks man... didnt see that :P

Did drop a PM to jimmy to ask to move the thread over to here, mind you, didn't realise he was the big boss at oople at that point....busy man :cry: (not sarcastic)

I had the same with my V12, but had the help from an experienced racer :

1 - Tyre additive, all on the rears, and about 1/2 cm on the inside of the fronts. Helps a LOT!

2 - changew the fronts, i got different compound (cant remember what, sorry!) and trued to IIRC 43mm

3 - if possible set the EPA on your car to less, so the steering isnt as 'much'

i did this, and went from an uncontrollable car one night to being regularly placed in the top 3 of the B final, and came 1st within about a month of starting v12 racing

so tyre additive is the biggest help, the trued tyres second and if you can set the EPA to control the servo motion.

everything else is standard.

IMHO cornering is the secret to V12 carpet, you can make it up on straights if you have the speed (i am brushless and race against brushed) but if you cant get round the bends you will lose time, and v12 is more about the corners than the straights.

I would suggest Jap 44-46's on the front trued to 46mm,and V53 or V54 on the rear as a start. Not all clubs allow additive to be used on Daves, especially those that run to the BRCA regs. If you can learn to drive without using additive,then you'll perform far better in a sanctioned race than you would using additive. Personally I've never used the stuff,I leave that to the 1/12 pan-car boys.

Grooved Foams / what's all this about then?

what does it do for tyre wear, handling etc

what are the benifits if any?

what’s the best way to do it?

Glenn, it lets the foams 'move' / flex more giving more rear grip, I found it made alot of diffference in both oval and circuit tracks. It does decrease the grip on the front though which is why I added 30g to the front which helped to balance it and also bring the front grip back.

No good having a good set up if your King Pins & Steering Blocks are binding. Take your time and make sure there free just like at the end of this video. These are used parts and on reassembly they needed some degree of wiggling to get them free'd up.

Rear Axle / Shimming the end float.

just shimmed mine out with a shim from 12th pancar axle. Had to file it out a little though.

one thing I might do instead is file the axle were the flats & shoulder are so the spacer can sit futher on.

anyone found any shims that fit with out the need to file the inner hole out?

How I sorted a binding ball raced wheel

Rear Foams

what's the smallest you can run on the rears?

Ground clearance dictaits this, most clubs adopt the 3mm ground clearance, with 1mm under the gear. You can keep the same gear ratio with a bit of calculation as the tyres wear down.

I have the spreadsheets to do rollout but would like to know the minimum so I can set the spreadsheet up. Maximum used would be nice also if anyone knows it.

Just read the following on a sale item

What effect & benefits does it have on the handling if any?

I have tried this along time ago, personally didnt like it, made the back end un-predictable and skipped out uncontrolably. Interested to see the reply. :confused:

You guys are talking setup, but I don't see what springs your using?
how far down are you guys doing the nuts up on the rear springs?
What additive can be used?
what shell is best?

Your answers please guya

Cheers Malc

What kick up on the front, and what does it give you?

Your answers please guys

on mine I have, hard front springs, on the rear I have medium with jap 52 foams on the front and pink mediums on the rear

Nuts, set them so you have 1 to 2mm clearance between the bottom of the motor plate and the chassis when you have the car fully loaded

2mm of washers between the A arm and chassis using the front mounting hole for king pin castor

90 % of mardave setup is rear tires
run silicone tube instead of spings on the front with 4mm caster on the front
rear should be 1mm of sag with soft spings
rear tires should be about 52mm
if ur cars kicking out run 52 japs on the front with superglue run around the outside rim if ur car understeers go down the compounds on the front
i was 2nd mardave national my brother was first
once u have the car balanced u should be able to run 100% on everything on ur speedo and crave more speed
rear diff should have 12 balls and run as loose as possible before it slips
and dont forget the nylon battery trays i make the cells run flat on the chassis lowering the centre of gravity and u can run ur cells offset to counter the motor
1st 2nd 3rd and 4th at the nationals
if u use lots of additive on the rear u should use 2 pairs,one one week then the other the next giving them time to dry out ,additive will soften the tire and ruin the that why one week u will go ace the next e final
then u can play with shells and small tune ups ,there the bits u fine tune the car with
