ZX5 FS2 Help

[Duncan]

I need some help, i am running on a high grip asto turf track and i am getting very bad grip roll. i have mini pins on the rear and mini spike on the front with the outside and inside spikes cut off. the car also feels a bit heavy. i cant get the feeling that i can cane it hard as it always rolls or flips in the corners. car also feels a bit twitchy. :cry:

Post up your full setup & I'll try to help.
Where is it grip rolling, on the way into, in the middle of or exiting the corner?
You will be best off running marching tires all round too.

The Lazer does generate a lot of grip but is also very responsive to setup tweaks

I see you are in Hertfordshire, what track is it?

Your set up you have, can we see it??

I would try, front shocks out on the wishbone 2nd hole in from the outside (assumeing you have the 4 hole tower) on the front shock tower.

Then run your front hubs low (spacer at the top)

Also try a front anti roll bar 1.1 or even 1.2mm.. also try your slipper unpinned to help with undulations on the track as the car takes everything in its stride this way. The only time i would run pinned now is on flat high grip carpet..

This seems to work for me, and i run big bores.. you could also try slightly thicker oil? I run Nick Gurnells tappered pistons... 37.5 front 30wt rear yellow front and red rear springs.

Also if you do run big bores, try your front link, inside tower with +1mm and inside on the hub +1mm

On this car getting your diffs right is essential.

Any questions drop me a line

I am no expert, but would suggest running mini pins will not be helping, try spikes on the back as they are more likely to slide.

The track is shrcc and the car can flip into and out of the corner depending on how bad i am driving.

Shrcc is mega grippy, I raced there at the regionals this year.

Be careful about stiffening the suspension up too much, as all this does is give you less warning when it's about to go. I ran my silverstone bwoc setup when I went there and that worked well. You can find it in the setup section on here or on petit.

Most of all the cause for grip roll is due to trying to carry too much speed through the corner. You can make things easier with setup and Tyres, but mostly it will be about being smooth and holding back more than you think.

I'd definitely agree that you want to match the Tyres front and rear. Spikes worked well there and will be easier than running pins. I'd at the very least trim the inside and outside of the front Tyres.

Hope this helps.

Well i bought the LAW44 carbon top dec mostly because it looks better then i bought a vega stearing link ( not sure why i did this as one of my complaints was too much stearing ) then i got the Law 43 1 day later after overcoming the guilt of spending too much money then there was a few other bits and bobs that all cost a fortune. I then had enormas fun fitting these parts using kevs set up and roger the Kyosho proffesors advice and i can not belive the differance in the car. grip roll has gone and car feel so much better and i have much more confidence in driving it , i also have gone two meetings without breaking a shock tower. Al i need to do now is fix my bad driving.:)

Glad to have been some help, anything else you need just ask and it will be a race between Kev, Tony and myself to answer .. the only kind of race with those two gents I stand a chance of winning ;)
