XRAY - Model racing cars

Hi all,
looking for some professional help here since Im quite new

basically i've been running my XB8 on an on-road track, Freedom/Rally Cross events, I've set front and central Diff with 500K oil, shoks with 1K oil with 8holes plate, lowered the the car 10cm front and 12cm rear but still I cannot get top speed and loose a lot on time on narrow tunrs
rear diff s with standard 3K oil, and roll bar are 2.6 front and 2.8 rear

I was thinking of adding a 3.2 bar front and 3.0 on rear, changing the shoks plate in to the 6 hole 1,2 and maybe put like a 1500 oil and a 60K oil for rear diff.
is that any good? any suggestion to get the best performance from the kit?

Thanks a lot
Antonio

Hello, this car was made for off-road so it will never be perfect on asfalt.
For sure you need
hard springs
Hard swaybar
Graphite plates for arms
Front 50 000 center 50 000 rear20 000
Piston6x1,2 should help

Hello

Here is link for chart witch springs: https://www.google.cz/search?q=xray+spr ... JI-lmCM%3A

There is all springs we made except 4 strip. They are harder then 3 strip.
For sure 500K will be better but I don´t want to write you this because some people will not understand...
Then try F 500K C 500K (maybe 1 000 000) R 100K

Good!
Try shorter link on rear upright.
Maybe also lower front upper arm and less caster.
