Default Stiffer suspension or tires with less grip?

After mounting new tires - Schumacher White with HPI hard inserts - my car got too much grip.

Which way to go? Other tires/inserts with less grip or stiffer suspension?

I tend to stick with my current tires and stiffer suspension, since the car this way will roll less and therefor be more responsive. But there are some bumps in our carpet track, so the suspension can be too hard. I tried another guys CS22 tires with medium Yokomo inserts. My car felt very balanced and predictable. But those Yokomo inserts aren't avaible around here any more.

I'm running an Sport2 with saddles and a one-way. Shocks: All 4 uses 80 wt oil with shock pistons no. 5. Equivalent to 60 wt oil. Springs, HPI: Front = Yellow (392 gF/mm), Rear = Pink (272 gF/mm) Sway bars: Purple up front, red in the rear.

Stiffer springs og tires with less grip? Any suggestions and especially why?

Ohhh, I see, a faster motor limit the chassis roll?

I do also believe in santa claus and the fact that the earth is flat...

If you like the way your car is rolling and reacting around the track then why don't you try changing your camber and toe angles. When you say you have too much grip, exactly what do you mean by that? Too much rear grip? Too much front grip? Cuz if the car is doing everything you want it too, what's the problem? If you're scrubbing speed because of the grip, then you should try different tires. If you just want to be able to do different things like swing the back end around tight corners, I would decrease rear camber. If the rear is too grippy and you're pushing...try a swaybar. I guess we'd have to know what you're trying to accomplish before a valid suggestion can be given

Ask Steve at Speed tech to see if he can deliver them for you. His Tire deals can net you rims, tires, and Yok inserts for about $30 US. You could try a number of things with the setup you have. I'm not too sure on your car but I would try to decrease the droop(less droop) on all shocks, which would yeild less weight transfer, less grip. Raise the ride height of the car is another thing I'd try. Or you could use more camber. There is a point on the camber of a tire that would actually start decreasing your traction is too far in the negative direction. You jcould also hieghten the roll center which would change the geometry of the suspension. The easiest thing would be to change the springs, but I wouldn't if your track is bumpy. HOpe this helps and I think what I've said is correct. I've only beeen in this hobby for about a yr though.

ok my mistake......... if u r rolling just get thicker oil and add swaybars
will slow down rolling reaction time
if u want get stiffer springs but cant tell for now gota test 1st
try the 1st 2 sugessions b4 adding stiffer springs

coz to me too much grip does not mean it should be rolling ....

ever see a car take a turn on 2 wheels ..... hehe.....

hm... droop yea...... on carpet u normally run totally no droop the suspension WONT drop if u lift the chasis.....
the ride height is the droop

if its hard to control add slight amount of droop in da rear

or if u want to do rear end flipping around more droop infront

cant really tell gota see and test it out .....to be able to give sugessions
mind explaining in a bit more detail??

Thanks for your replies.

Okay, by too much grip I mean my car roll way too much. I've never before had problems with the body touching the ground. There's plenty of room between the ground and the body, when the car stand still.

After thinking it over again, I've choosen to go with the CS 22 tires.

My car handled like a dream with those tires, I tried.

They got a lower profile than the Schumacher white. They are 24 mm, instead of 26.

I already got a suspension, which is quite hard, compared to the bumps in the track. Those bumps are also the reason for why I need more droop than you usually do on a carpet track.

I've bought Take Off CS 22 with medium inserts included. I assume it's the best to belt them like I did with the Schumachers? That is, two times gaffa tape?

Of course I will explain.

Gaffa tape - I dont know the english word, but it is a special tape, which got very small threads built in, therefor it's very strong.

With belt, I mean mounting some sort of tape inside the tire. This way, it dont deform at high speeds and the belt extend lifetime to around the double.

imataquito: Sorry if I was a little rude about the one with the santa claus...

ok np cole ....
hey .. duct tape .. which has the cloth like texture ???
hm wont that increase the weight of ur tires..... make u slow and make the car/suspension bounce more coz the tire wont be totally round ? make the tire vibrate and the whole car unstable
and ... slow down ur acceleration

i think its disadvantages is more then its advantages coz u will also increase unsprung weight which makes ur handling CRAP

i haven tried this method but i think if u want to belt them like u said ... try glass tape ?
dont shoot me ... i was just merely sugessting to use glass tape ... coz its thinner... just as strong and lighter .....

but since racer dave said its already belted then no need o belt them....... just use harder inserts ...... insted of soft ones

ur tires will last longer with hard inserts ...... and choose a insert thet will NOT give u any air gap between the tires and insert
it will help it last longer ......

and if u r challenging for TQ and pole dun worry about tires
the joy on wining the race outweights the cost
so use soft inserts
^ this depends on track tho ...but most A-mainers use soft inserts

Here's a pic of gaffa tape. Sort of like duct tape.
