Trails or Downhill?
These might be a little out the way: http://www.7stanesmountainbiking.com/
Bit closer to Aberdeen: http://www.glenlivetestate.co.uk/
There are lots of non trail centre places too but the weather is getting worse up in the Highlands that you might be a little limited.
There are also some trails near Stirling University in the woods by Dumyat/Blairlogie (https://www.google.co.uk/maps/place/56%C2%B009'27.9%22N+3%C2%B052'33.2%22Wfirstname.lastname@example.org,-3.8918322,3055m/data=!3m1!1e3!4m2!3m1!1s0x0:0x0 park here: https://www.google.co.uk/maps/place/56%C2%B008'52.4%22N+3%C2%B054'16.3%22Wemail@example.com,-3.9067087,741m/data=!3m2!1e3!4b1!4m2!3m1!1s0x0:0x0). Also Carron Valley trail centre near Falkirk but it's pretty basic.
Hoepfully Ross will be able to post some stuff closer to the Glasgow area.
A quick yet successful half hours work tonight. I've had a mystery knocking that came and went on the N/S front, but there was no play in any of the suspension ball joints, links or bushes.
Decided on changing my lower ball joint as they were presenting the most worry having seen the damage they do when they let go. The oem unit that had done 66k still feels good in fairness and probably would have gone on another 60k odd but I feel better now it's changed. Knock has disappeared so quest successful.
Tempted to change both the new one and O/S front to either proper OEM Honda units over the factors copies or go for some extended ball joints.
Top end thrustmaster kit is the absolute dogs bollocks, my 20 year old flcs and tqs still work fine if you have a game port that works (nothing past win xp) and my rcs rudders work exceptionally well now I've converted them to USB by cannibalising an old logitech wheel for the pots and boards. If you can afford it then it's very good kit, my warthog hotas is going to last forever and only cost me 170 quid :)
