Front shock angles and mountings..
I'm arsing about in CAD deciding where best to put shock brackets for the front. Mounting underneath the top rail looks favourite for top
wishbone clearance and such, and lets me get the bottom bone bracket right up against the balljoint.
Anyone know what's the steepest angle GTS shocks like to run at? Any other comments on my bracketry?
I'll u2u doz about this posting, of course.

brackets
i cant comment on the shocks but i think its a good idea to have the brackets as close to the ball joint as you can especialy when you have a heavy
engine like the rv8 also have a look at the thread with the bent whish bone that guy was also using a rv8 i think the conclusion was to use larger
diameter tube and or thicker wall tube to over come the problem
good luck dave

the more you lay them down, the more the effective spring rate falls.

Coil over angle
A damper is a displacement device, in other words it works when it moves and the more movement the better especially with cheaper shocks.
Therefore you should position the coil over so as much wheel movement as possible is translated into damper movement. So if the wheel moves up 25mm
the damper should ideally move 25mm (a 1:1 ratio). This also means you can use lighter springs and compare wheel rates easily.
From a structural point of view the coil over mount should be a close as possible to the lower ball joint to avoid a bending load on the lower
wishbone.

Don't get too hung up about it, in reality on the Locost you have two choices, on the side of the top rail tube, or underneath it.
Third option is to send me an email to remind me and i'll stick some specially laser cut plates that position the shock mount in a compromise
position between the two.
How about that for customer service?
Kind regards,
Darren

That's cool, thanks darren. But I was just after something like "ooh don't run them more than 45 degrees or you'll get gas in
the valves" or somesuch. I think I'll bung them under the rails.
Happily, I have a little friend who works at a fab plant with a laser. he's going to cut my wishbone plates and such for me
