He's wanting to shorten them because spring rub and doesn't want to go in there twice. Basically lop off every inch he's not ever going to use, and call it a day.

 

I'm concerned about spring rub, not top hat clearance.

 

I ended up lopping off 5 threads from my front sleeves. I have room for even more. I haven't driven my car significantly yet but that should be enough to prevent any spring rub.

 

In that case, no. I have not seen any that are both high quality and a uniform ID. GL fam

 

Was only able to get -1.1 camber on the front at 12.75 ride hight.

 

Its cold and raining now, so I won't be able to test for a few days.

 

Just a revalve option. They seem competent but I may be the test subject if I go with them.
The guy who used to do mine isn't doing them anymore, and Henderson won't do our lowly shocks now either.
RE Suspension (below) is $300 for four Bilsteins so that isn't bad.
I'm also talking to Inertia Labs.

There are a lot of shops that'll do revalves but seems like a crap shoot.
A sticky on revalve options and outcomes might be useful(?)

Consider extended ball joints. I wore mine out within a year likely from aggressive track driving. I got them from FM and the manufacturer covered them under warranty. Easy camber plus a bit of track width to even out with the rear.
From memory, I have about -3° front with a ~4.25" pinch weld ride height. The alignment shop was getting maybe -1.8° with the stock ball joints.

 

 

I think i offended Maruha somehow. They have not responded to any contact attempts. About par for my luck.

 

I've used Bill at @MiataRoadster for stuff I've gotten from them in the past.

 

It's honestly a bit late for me at this point. I kinda needed them this weekend, and it sounds like they would have been here if i had gotten any response when i started contacting them. Oh well.

 

They're nice.

Came well packed:





Have class 10.9 studs pressed in:





Better quality than I was expecting, if I didn't know otherwise i'd say these look like OEM items:

 

Found these alloy helper spring couplers - have been looking for cheaper ones for a while. Look decent and not as pricey as eibach ones:




I just bought 4 including shipping to me for approx $60 USD - will report back on what they're like. From: https://www.motorsport-tools.com/mot...al-locati.html

 

 

 

If you have access to a lathe you can make a sleeve to press into the shock eye and use the cheap 4$ NA bushings.

 

 

Anyone have tips on how to get Maruha to respond to you?
