That is just one of the adjusters for the front remote damping adjustment. It allows you to adjust the damper **** easier. I never installed them, they get in the way.

I dont like the redesign and possible implications of a non-reinforced factory upper strut mount (rear). The sheet metal in that area does not looked designed to take those loads.

I would almost say the same thing for the OEM rear axle lower strut mounts.

I have had mine for two seasons and over 10k km, still like new.



Here is the milling that was done to prep the lower spindles before tig welding. Do not skimp out here, take time to find a very good welder that will preheat the casting and tig weld.

The update is they're still dragging their toosh and not providing any customer support. I haven't heard a peep in months, and I even had to call them out publicly on social media before they would even acknowledge me. Their PR guy took it to email then promptly forgot about me. I told them if they want to continue using my car as their promo they need to fix this, otherwise I will continue calling out how bad their product & support has been.

I'll post updates if/when they send the updated rears.

The line circled in the image is a remote adjuster **** because they invert the front struts making it so you have to drill holes in the side of the strut tubes to attach the remote to the bottom. Poor design and not actually tested on their end more than a lap around a track on a dry day. This allows standing water inside the strut tubes on rainy days, making the control arm bolts that live underneath the spindles rust. Make sure you coat the **** out of them in rubberizer.

If I decide to throw another few thousand at my suspension some day, the ACBRONS are definitely top of the list. I've heard great things.

(Still) anxiously awaiting the mythical Stance redesign....

The struts can hold coilovers just fine. Racers have been tracking FB/SA chassis with strut tower mounted coils for decades. Even with decent abuse there is no strut tower movement.

To clarify - you HAVE the new redesign? Have had it for months?? Time to fire up the social media rants again.... *sigh* Can't wait to be done with these guys.

That Mustang shock MIGHT work - things you have to consider: Eyelet width of the lower bolt mount, outer-diameter of the upper spring (1.9" is about all we have to work with up in the strut towers), and total length measured / sag compensated @ given spring rates. Its kind of a trial-and-error process without static (non-adjustable) coilovers like that.

Well, it sucks to be seeing my hunches about Stance playing out. I'm slowly working on a front solution for a race project with another company using their stuff but it's one of those things where I'm just trying to sort out stuff close enough to work for me.

ioTus- The ACBRON Motorsports coilovers are the best I've seen so far but the price...geez.. I can buy another car with that lol. But I would love a set of these.

I have the original design, pre update.

I got mine from Race Consulting Agency 2 years ago or a bit more.

Iotus you helped give some feedback, I remember they shipped you the wrong length front dampers and you had rear spring interference issues.

I had good customer service from RCA and my rear doesn't seem to have any interference issues. No noise etc.

I know there is good experience with the coilover mounting in the OEM damper position but it isnt something i was comfortable with. TTT is the same design and that is why I didn't go with TTT...I have the rest of their front end hardware however.

When my car comes out of storage I will look into that water issue. I coated the inside of my spindle casting with grease. The lower ball joint nut and lower steering bracket aren't in that cavity though. My strut casting is closed at that end, so the ball joint nut is essentially sealed/sandwiched and protected just like OEM.

edit- ACBRON stuff looks amazing. Wondering what else they will come out with. I think those prices are AUD, so you US guys can take away 20% !

Techno Toy Tuning is still an amazing option. Amazing customer service etc and the best parts you can buy for our chassis. I wanted to keep the parts on a shelf to admire TIG and powdercoating haha.

That ACBRON stuff is nice, but even at USD price, those are expensive. Through shipping on top of that.

Considering how much time and money Iíve wasted trying to make the Stance coils work, those ACBRONs are a steal. I WISH i only had that much in my suspension investment.

Sometime you get what you pay for, and honestly thats an average price for high quality adjustable coilovers.

TTT is OK from what I can tell, but its not truly height adjustable for fine tuning stance and corner balance.

I had some ACBRON coilovers arrive a couple of months ago. Really nice design and adjustable from the top (with supplied adjusters). Unfortunately won't have them installed for a good few months yet. I don't have any pictures on this laptop either haha

I have the ACBron front coilovers in mine with rear to be installed. It certainly helps being in the same city, but I can tell you the quality is amazing. And he is a lifelong rotary fanatic. He has owned 8 RX-7s or so (I've lost count), including a couple of builds that he has written about here. Unlike many other designs, which have been adapted from products for other cars, these were designed from the ground up specifically for RX-7s and tested extensively on local race cars and street driven cars before release.

Have any of you guys ever try to run AE86 rear lowering springs?

Why bother when you can get 5 inch diameter circle track racing springs dirt cheap in almost any length and rate that you want? They fit just fine in the rear of an RX7.


you can even get some snazzy adjusters so you can dial in your ride height if you want. I have adjusters on my rear springs but I think I will remove them so save some weight, I can still set corner weights with the front coil overs.

Bonus tip, get a 5 inch diameter 16 inch long 125lb spring, cut it in half and you have 2 8 inch long 250lb springs. The cut end will actually fit better in the lower spring seat of a stock RC7 than a flat ground racing spring.

issue is usually springs are rated over the WHOLE length of the spring.. you cut in half you change the tension rate... but i could be wrong

Yep, you're wrong. Coil springs are torsion bars packaged funny - halve the length, spring rate doubles, like he said.

For some reason i thought a spring cut in half had 4 x K. Like say a 16' plank cut down to 8'.
