Hi Eric, there are a lot of discussion behind setups in which I also have my own theory for S710. What you have set your car up now, you have the most front grip but the least rear grip (once again, according to my theory). If you have time, tried what I suggest and see if you like it. Furthermore, when the front roll center has no shims under, it also means to some extends when the arm/suspension compressed, the dogbone will hits/rubs with front upper arms bracket. That is the reason I always use up to 1mm shims only and if more front traction still needed, I will look elsewhere.

You can get more overal grip by using optional 802121 low chassis.

And yes Eric, I choose to believe higher roll center = more grip.

I tried raising the rear roll centre in practice today and hated it, rear end was very loose, so dropped it right back down and the rear grip came back up, but still needed some more front grip. I ended up increasing the front caster to the maximum and changed my driving style abit. In the end I top qualified and came second in the final. Overall a very good day and some improvement in car set up.

Snake-If running smaller tyres on the front doesnt work for you then try 42 or 45 fronts.

Hi Mike,

If you don't mind me asking, what tyres do you run on the Serpent at Ruapuna? Are you using a Mega? If so, any changes to the gearing?

Thanks,

Trevor

Default Rubber Tyres...

Hy guys ..
I've been reading around... and wanted to ask a few setup questions..
What's your advice on running with Rubber tires !? .. they give less grip then foam ones.. and of course, with a front diff, because with one-way the car will spin on breaking ... at least that's what everybody i know says.....
Any advice on what to do to get the better performance out of the car.. with that kind of tires ?!!?..
Thank you

Rodrigo Meira

thank you all for help guys. greg, i'm gonna change front tire size today on track if i find truer. if i can't, i'll use 3racing setup tires, might be a little thin but no problem . pyramid, i'll try what you suggest to me. i hope this will solve my problem. now, i have to find easy to drive setup which includes solid diff. and 21t side pulley.

With solid front, try the following setups: http://www.mytsn.com/setups/setup.asp?sid=2942

My setup above was run on very technical track using the following optional items: low chassis 802121 and optional long servo saver. PS: do not copy front and rear camber reading, you need to used your own on your particular track and at particular layout. Just make sure front wear evenly and rear slightly conical (inside).

With 21T, use 3mm smaller front tires.

When I drove last time I noticed that my rear tires were getting conical to the outside, this even with the 3 degree rear camber setting? How far could I go? 4 degrees sound a little extreme to me..

OK, I'll try that.. The track is the pretty big Staffanstorp track in the south of Sweden, the host of the 1:8 A-euros next year. It's nice and flat, but when the temps are high the tire wear is real high too, which you can't understand after looking on the flat and smooth surface..
