Did they get back to you? I asked them, and they said there is only 1 length offered…

they did but only asked where i purchased my LCA from so far.

Guess i will see

No problems with mine. 2 sets of 18” Apex wheels. I’m on coilovers, SPL arms and recent replacement bolts.

Previously my arm was in the wrong position and rubbing. That was corrected, rub gone. Not a bolt issue. These are two separate issues, not to be confused. Bryan (@razorlab) noticed it right away.

Yeah maybe the standard bolt is shorter now, and that’s been corrected. Would be nice if their customer service would provide some context in their email responses

It’s shorter now. I would just ask SPL for the revised shorter studs. What they have listed here https://www.splparts.com/products/lower-control-arm-replacement-stud-kit-g29.html

Agree with razorlab. I too have the new stud and they are shorter and fit 18” wheels no problems. When they first revised the bolts they were too long. So just need to get the. To send you the correct one.

SPL got back to me and they need to manufacture the new studs so it will be a couple of weeks before they get sent out to me.

Im pretty happy so far with their customer service.

cheers

Also for others if you still have the original bolts they will need to be changed. I broke both of them on track and luckily in Both cases was able to to go off track straight and stop/ get back to pits. But this is a bad thing if you break one even on the street. Here is what it looks like broken. Both broke in Same spot.

Yeah, my mechanic replaced both and SPL sent me both. Looks like mine broke a bit further down. Regardless, neither one wanted me on the old bolt. Kudos to you guys shouting out.

Was like ice skating when she broke. I had to limp off track, fist in air, peace symbol at the corner workers not to black flag the rest of the run group, lol.

Thank you for mentioning this. Any other SPL components I should be worried about?

Camber plates are all you need unless you think you are at tip of spear time wise on any track. I have run very competitive times and won stuff with just camber plates, sway bars and oem suspension for 3 seasons with nothing breaking. The challenge if you buy and install the entire suite of Verus products is: you have added multiple potential failure points, bolts, etc. You have also introduced A multiplier of adjustments that you may not need, over use, get confused. The OEM geometry is very complex and reacts very differently under load sometimes than what you "think" it should do.

I am not against SPL- 90% of their products are fine. 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.

.02 and maybe not worth that

Just to add in support of SPL. I was one of the first to break these bolts. So I talked to them even before they had the new ones redesigned. They have been very good support wise and they sent me the spherical bearings as well as bolt to change. I have all their arms on the car and 80 + track days on them since 2021. I also have gone to full slicks and am TT2 level run groups with big brakes etc. so defiantly have stress tested all of this stuff. I am not concerned about their parts. Race car stuff eventually breaks and wears out.

Uhh...nobody is talking about Verus here.

Response I received from SPL:
"There was no issue with the old bolts, the problem was improper installation due to not fully reading the instructions. Follow the TSB, and use that to determine if you need to get the new stud."

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.

I agree that it is not just installation on the old bolt. I ran through two sets of these. And they were tight. In fact the stupid nut on the first ones was so hard to get tight as it us a metal tab lock vs nylock I had to use two big beaker bars to get it on plus the torque wrench. I can see their point if they were loose then the design allowed for play which could bend the bolts. But I talked to the main person early on when first failed and the new bolt design significantly ups the failure load required to break it. Hence the redesign.
