ZX-5 SP 2008 setup help needed please

[HOTSHOT III]

Hi all,

Did my 1st meeting at TORCH on Sunday 15/07 and enjoyed myself but found it very competitive as I guess anyone would on their 1st time at a new track.

Can anyone suggest ways to improve the car for this track? I didn't seem to have enough steering through the twisty section before the back straight and towards the end of the day just couldn't get the rostrum jump section right. Eventually I gave up trying and just rolled over the 1st jump to stay safe which did actually work quite well as I finished the day without breaking anything!

This car is not an FS2SP but the older SP 2008 (the last version Kyosho made with all the cells down one side before changing to the FS configuration). I'd love an FS2SP but I have a truckload of new spares for this car and the batteries I use in my 1/8th buggy fit, so I guess for the time being i'll be staying as I am.

Currently my setup is:

Front

Shumacher green minispikes with std inserts (medium U6733)
Shocks 30w oil, std pistons, yellow springs, top inner hole, bottom middle hole
Ride height 18mm
No sway bar (but I have 1.25mm and 1.6mm items)
7 degree caster blocks
Inner top link ball on inner hole, no spacer
Outer top link ball on outer hole, no spacer
No spacers below inner/outer steering ball links
Front diff installed (have never tried spool/one way)

Rear

Shumacher yellow minispikes with std inserts (medium U6734)
Shocks 30w oil, std pistons, yellow springs, top middle hole, bottom inner hole
Ride height 18mm
No sway bar (but I have 1.25mm and 1.6mm items)
Inner top link ball on inner hole, no spacer
Outer top link ball on outer hole, 2mm spacer

This is pretty much the kit standard setup for the car but the only other place i've really raced it is at South Coast RC where it's much more bumpy and the astro is a lot more grippy (it's like a thick pile carpet) so I think on Sunday I might just not have been pushing hard enough for fear of griproll, but it would be good to hear from anyone who can help.

For example I noticed one A finalist using the 10 degree caster blocks on their FS2, do these generate more steering or less? Thanks!
