Front wishbone - another weak point?

Just checked the 501x arms against the SX ones and they are a country mile out.

Certainly a wise idea for a track with big air like Newbury (and a driver with skills like mine ).

Yup, just seen those:

When the shocks are limited enough to reduce the outdrives letting go the car runs out of suspension travel with the chassis about 5mm off the deck

put like that then think on the £'s youll all save on undertrays

Ah....

Mine neither.

Never had any issues with front up travel - never bothered to limit either!!

However, i think i have seen this style of breakage before - well, not technically true, as mine never got that bad, but I did crack one.

I think the "issue" is probably the small step that is in the ball joint - the top part that isn't threaded. When you screw this in, i think it stresses the plastic big time. I think i cut a small chamfer/countersink with a sharp scalpel, so that the step has somewhere to go. I haven't suffered this issue since.

I have just checked my car, looks like i probably have s shorter ball joint in there than is in the kit. Not sure if this makes any difference or not.

are you running your diffs in the high or low positions?

[Northy]

Std low......

When my chassis is on the floor I still have 8-10mm of shock travel left. The blind part of the ball stud being forced into the wishbone and cracking/stressing the plastic sounds entirely plausable. Thankfully mine look ok. Good idea tho putting a chamfer on the edge of the hole giving it room to tighten up flush.

I do like to read the Schumacher threads despite me not having the car, anyway................................

When Losi brought out the new (shite) graphite with the small writing on the XX4 front towers, I broke off 2 front camber link mounts as I installed the ball end for the first time becasue I used a TI ball end that had a small shank and as that tightened it it opened up the hole and 'SNAP' off she broke.

Surely if you pop that bottom shock mount on and off a few times for setup/cleaning etc it's going to wear quickly? Wouldn't an eyelet like Losi/ AE etc be better?

[MattW]

Dan, wear isn't generally a problem to be honest.

The Eyelet isn't a bad idea in principle - however, you would need to use an imperial screw - because metric would be too fine and would fail in no time - this is speaking from experience!! So, you rely on the 4-40 screw (2.45mm ish!) being ok in a hole that is intended for 3mm. It would probably be fine, but a bit on edge. The other thing with that type of fixing is that is actually has a fair amount more leverage on the hole IMHO, so is actually more likely to break out.

Resurrecting an old thread, but would the flexi wishbones improve traction? Has anyone tried them?
