[6pack] Race Car Quandry

[Navarrette, Vance]

        RML:

        Looks like there was a chipped edge on the casting, and the crack
proliferated from the chip. Could it be damage incurred on the race track?
Might be good to look for other chips and sand/polish them out of the
casting.
        This *IS* one of the places that the castings are known to crack,
however. What modifications have you made to the suspension? Coil over shocks,
sway bars, etc?

        Cheers,

        Vance

Hi,

I was doing a normal pre-race check on the race car last night and found
cracks in both rear trailing arms.

I guess I need to deal with this:

I have to be honest, I haven't looked at that part since I installed the
trailing arms in the spring (I put in new nylatron bushings), but that
crack seems like it's been there a while. I must have not seen it while I
was installing the bushings. Yikes.

Opinions?

regards,
rml
