You sir, are a mufuggin savage. Thank you.

Had the same problem with the msm when installing my coilovers.

thumpetto007 07-07-2018 11:57 PM

Same issue for me. They clearanced themselves, lol

NB2 arms have the extra brace, as noted above.

However, that alone is not normally an issue. By chance, do you also have ELBJs or offset bushings installed and are running less than -3* camber?

icantlearn 07-08-2018 02:01 PM

I have ELBJs. No offset bushings. -3* front camber.

This is a new issue. I think it started happening after the ELBJs were installed but im not sure.

I have not seen/heard of this issue before with cars running ELBJs. So if there is a bigger problem then I dont want to order new shock bodies just for them to get gouged as well.

How thick are the shock bodies? I feel like there is barely anything left.

You realize that there is probably 1mm left in the shock body right? Self clearancing is not the solution.

thumpetto007 07-08-2018 03:10 PM

Im riding on blown out zidas anyways :)

ill be grinding the tab down on the control arm, but mine isnt as bad.

icantlearn 07-09-2018 08:55 PM

I will be grinding mine down as well but im not sure that is the whole issue.

Sometimes you just gotta grind a FUCA.

So are you saying that is the reason why its rubbing Emilio?

doward 07-11-2018 12:35 AM

Like I mentioned on the phone, the issue is a combination of
- NB2 UCA gusset takes away precious few mm of clearance.
- ELBJs that add too much camber for your current usage/height/whatever, so you've:
- Minimized camber with the cam bolts, which pulls the lower shock mount, and therefore shock body, inward towards the UCA gusset.

The very few cases I've seen have been NB2 only. This does not seem to happen on 90-00 suspensions, but Mazda has superseded the early arms with the NB2 part number. We will only see more of this going forward.
Adding back some camber with the LCA cam bolts will move the LCA and lower shock mount out away from the gusset, but may not give you enough clearance by itself.
Grinding away part of that gusset will make some room, but may not give you enough clearance by itself.

Ok so heres the thing, I was not able to achieve my current camber targets with stock lbj. Also, if this is something you have seen before, its really, REALLY important to state this on the site or something so the customer knows about this issue. How am I supposed to know that this would happen? Its completely unreasonable to expect a customer to disassemble a shock and stick it in the car and do a stroke pass when there is no documentation of an issue such as this. So now im stuck with an $800 bill for new dampers. I will call tomorrow and see if we can come to a reasonable solution.

why new shocks? Did you grind a hole all the way through?

icantlearn 07-11-2018 12:29 PM

its too close for comfort.

Yep. No way would i run that.

icantlearn 07-11-2018 12:32 PM

If I push on the center of the damaged area, I can feel the metal flexing. Its paper thin.

icantlearn 07-11-2018 12:43 PM

Also, for what its worth, the bump stops dont really do anything.

this is *Just* before the wheel starts to make contact with the fender well. Already well into bump stop.https://cimg0.ibsrv.net/gimg/www.mia...5205b3c212.jpg
https://cimg4.ibsrv.net/gimg/www.mia...0337b28192.jpg

And this is where the bump stop is maxed out. So a 1/2" of extra wheel travel that is not needed/supposed to be there/"safe".

https://cimg9.ibsrv.net/gimg/www.mia...a2592e3725.jpg
https://cimg1.ibsrv.net/gimg/www.mia...9eebac3eb8.jpg

And this is where you just start to touch the bump stop. So there is a whole inch of bump stop travel. This would have been fine if the bump stop was firmer and progressive to keep the bump stop from compressing all the way but still not be harsh. But its way too soft.
