Mardave vs the Superstox - General Chat Discussions on The Offical Mardave Forum

Jaykelvik

Hello all Jamie Oldman here

So today at Risby running the same set ups on both cars (silver can 4 cell) i found the mardave to go 1, 1/2 laps faster then the Schumacher but only problem is the Schumacher didn't have a diff in but was faster then the mardave in a straight line

I ran the exact same compound tires on both cars contacts rears on both cars and the 42s on the front , only reall differenced is with the mardave i could carry a great deal more corner speed where the Schumacher i literately had to roll round the corner (but again no diff so this is normal)

but in all the Mardave ran brilliantly all day again i just missed the A final and managed pole in the B final for the second week running (maybe its time to actually swap to 1 cell brush-less and say bye to the 4cell set-up :(, ) but after testing both cars i shall be staying with Mardave its a solid built car and easy to set up , and i notice any changes i do to the car how ever with the Schumacher

I changed the rear spring positions each race and noticed no difference what so ever ,

I finally settled on mid position for the rear springs , i ran complete kit springs all round to make the mardave a little softer and it worked at treat grip rolled once , however that was the only run that i applied additive to the tyres after that i found no need for additive and the car was amazing , so all in all i prefer the Mardave.

so any more who runs both cars? , quite a good piece of info here :)

I run both cars but ive been a long time fan of mardave :D and of course shall always be a mardave driver

Now im wanting to move up to national level to try my luck now we have a circuit mardave series :)

and hopefully the rugracers series really looking forward to that.

Well, I don't own a SS but I was able to have a try with a borrowed one last night. Comparing the way it went to my trusty V12 the, V12 wins hands down!

We had an extended meeting at WSMCC yesterday, so plenty of track time for testing and setup changes. There was a good turn out, about 16 drivers in total in the GT12 class and a fair mix of the two cars. Due to recovering from hand surgery I was only able to do the first two qualifiers with my V12, but I spend the rest of the day observing how the two cars compared on the track.

The SS looks way more pointed but unstable - twitching into the corners as you enter, then a bit of pre-apex push and under-steer before really leaning its shoulder in and biting in hard at the apex. There was no smooth line through the corners, most corners look like a 50p piece! It also looked like most drivers were having to "hurry up and wait" before applying power out of the corners too, acceleration and steering at the same time was a sure fire way to point the wrong way down the track!

As I said, I was able to try one for myself. I was polite enough to wait until its owner had done all the hard work and get it as dialed as he could and then try it :-) Not nice. Not smooth. Not consistent. No way on Earth I could race that car, just surviving from one corner to the next was hard enough! For me, the lack of smoothness and consistency was the problem - sometimes it would under-steer, sometimes it would spin, each corner was different and you could not predict what it would throw at you next. Five laps was all I could stand! With my V12 I can really get into a flow and rhythm, the car is extremely predictable.

I think the front and rear geometry is to blame for the SS handling. The front end seems to have a lot of castor when set up which will make the car reluctant to turn in. Come mid-corner, when the suspension is compressed and that roll-bat wishbone link kicks in, castor reduces, the front dips, you get a bigger tire contact patch gripping the track and the front bites to hurl you through the corner. That explains the front. The rear is different - it is a very smooth action but there is no anti-squat with the way the kit is set up, and I think this will result in more grip being generated through the rear end. Not always good though because the rear will grip, grip, grip and then SUDDENLY let go when the tires can give no more. I think the V12 will have a fractionally lower ultimate grip level, but it will slide gently as it approaches its limit. This will make the V12 smoother to drive hard. I'm not sure the absence of a diff is the whole story, many drivers I know do very well indeed with no diff in their V12!

Another issue is tires. I think the kit ones are not always the same (at least two cars I have seen have been supplied with tires that definitely feel different!) and probably not an appropriate compound either.

The SS drivers I have spoken to have tried all sorts - different front and rear springs, different spring tensions, different ride heights, different rear spring positions, side link angles, center link lengths, rear damper o-rings, tire compounds... It all seems a lot of effort and no real results on the track.

For me it is Mardave all the way!

Cheers all
All I can say the simplicity by design moto is a little strange with the amount of bags and screedetc in a kit
But will have a place on someone's shelf

i second that Mr M. it's eyecandy for sure, but it seems too evolved to quickly work on or dial things out,

one thing that i can see is that you instantly get aloy motor mounts and some trick bits for the same price as the ceCarbon,

rather eyeballing the ce anyway for simplicity sake
