Anybody seen this before?

Current plan is to trim the body and see if that helps.

Why not try some bump stop packers in the short term before cutting metal out near the shock tower?

aidandj

iTrader: (5)

Because i'm lazy and would rather cut than pull a shork. Also i dont want to lose travel. I think I should be able to trim it out a little bit and be fine. I believe the lower is also contacting the subframe somewhere.

Packers are slitted so you can pop them on the shaft without pulling the shock.

Maybe not the ultimate solution, but it gives you time to investigate without cutting up your car.

aidandj

Ahh, i'll look into those. I really don't mind cutting the car. And it looks like as long as I bend that lip back up it shouldn't matter a whole lot.

But yeah, the packers are just cut plastic ring things that you pop over the shock shaft. You could probably make some with whatever you have laying around.

That, or stiffer springs to keep from bottoming out.

I doubt stiffer springs will help. Unless they are like 2000# springs. These are from hard slams, not turning or anything.

Stop offroading your Miata?

im not surprised with this at all. more spring will help for sure. i ran around 3 degrees camber once out back and hit a curbing just right that the bolts holding the shock mounting area to the frame cut into the backside of my rim.

also gen2 ftl

You really think an extra 100# of spring will help this.....thats not how this works.

Why gen2 ftl.

I'll take a photo of my LR corner with the exact same parts at full bump w/o spring for comparison tomorrow.

aidandj

Do it with and without a bumpstop too if possible so I know how much the bumpstop has to compress to get to this point.

afm

iTrader: (3)

You're killing me.

But seriously, I think there's no way I can photograph that perspective showing the bumpstops with the billet mounts.

aidandj

iTrader: (5)

Don't need pics. Just measure from the top of the billet mount to the top of the shock when control arm touches body.

iv handled both gens and gen 2 have a cheaper build quality.


what ride height are you out back. and did you go from nb top hats to billets and the contact is a side effect?

aidandj

iTrader: (5)

Always been on billet.

afm

iTrader: (3)

Gen 2s have bigger pistons and are doubly digressive. No idea what world that's "FTL" in.

Ride height also doesn't matter here.

excuse me i get caught up in perceived quality and value too easily.

back to the topic

what are our options here.

bent arm thats bowed. shock body is too short. bump stop is too short. upper shock mount is too high.

the idea of more spring is to keep the suspension off the bump stop as much as we can.

can you pull the spring out and check for contact when the shock is just touching the bumpstop?

aidandj

iTrader: (5)

Arm could be bent. I could put a straight edge on it tonight.

I'm far too lazy to pull the spring out. If I go that far I'm just going to cut where it is hitting.

AFAIK i am the only person with this issue, which theoretically rules out shock, bump stop, and upper shock mount issues.

I wonder if there are just differences in each chassis.

mmmjesse

either stop doing sweet jumps or dont be so stanced bro.

JJFU. I have never seen that kind of contact before and i have had some dumb low miatas in the past.. Do you know when it did it? i imagine you would have felt it bottom out.
