SPL front lower control arm clearance issue

[lucky phil]

so they revised a part that had nothing wrong with it, and only broke due to improper installation.

So they’re basically saying…. this new bolt can’t be installed incorrectly, and therefore has no chance of breaking.

Well from an engineering perspective it may be a case that with the original bolt assembly there's not enough headroom in the bolt spec to cope with the typical home mechanic instillation torquing tolerances. So installed and torqued correctly it's adequate but the replacement of the plated bolt with a longer stud gives more tolerance to the torquing process. Saying this is a possibility. Noting also that the new stud is longer overall which means when its torqued it's under less strain than the shorter original bolt. It's also phosphate coated by the appearance which is used for high strength fasteners in preference over zink plating which can lead to failure in high strength fasteners due to hydrogen embrittlement. That's the reason quality 8.8 grade and above metric fasteners generally aren't plated. The new stud is possibly a grade 10.9 or higher.

I just think people tend to think they need something that they don't because racer X uses it- and then they over think or over adjust.

Race car stuff eventually breaks and wears out.

Two common sense brilliant statements ?

Wish I read all of this before purchasing...

Anyone know if the new bolt clears 17s inch wheels ?

I just received a set of LCA directly from SPL so assume it's the new bolts.

I'm lowered and reason for change was to remove some camber,
But need to know if 17s fit to run front skinnies before fitting this.

I have drag weekend coming up in 2 weeks, no time for messing around now.
