Is Moton also AST?

Maybe just go koni yellows when the oe wears out, I'll get the rebound damping but no corner balancing.

Get with Charles @ Powertrix.com. He is close to you and can hook you up. Give him a call. He is very knowledgeable.

As for the rear sway bar, leave it stock.

This is fantastic info! Thanks man, I'll check each of these. i've been reading as well and sounds like numerous people talking about shock bushings being upgraded as well? Also Rear Shock mount reinforcement? I'm curious with the different location than OEM if this has caused any serious headaches on install. I'm taking it to a shop to do so, but I'd rather not have to do some major overhaul if I don't have to.

JRZ RS Pros MSRP is $5,665 off Forged Performance's website.

This is great. I'll need to narrow down my search to comparing AST vs JRZ then. I automatically wrote them off bc the only ones I saw in a quick search were $8k and then another for around $15k.

These are really good coil overs for the price!

You would benefit from doing the SPL lower shock mount bushing when you go to a true type coilover, but its not required

. There is really no need to brace the shock tower when you switch. Install on a true type coil is about 20 minutes per side, not including taking the spring bucket arm out and replacing it with an adjustable arm.

If you're comparing AST to JRZ, I would go JRZ hands down. AST's dont seem to last long on heavier cars except for the BMW guys. I would be looking at JRZ and MCS if you want something at that level. I will be going with JRZ next year hopefully.

Any actual data to support this? As far as I knew there were only a handful of people to use AST shocks on a 370Z. I don't recall hearing/seeing any complaints about them.

It's from what I remember doing research into them a year or so ago. They didn't have a good longevity record on heavier cars, so I stopped digging into them. Let me do some looking and I will see what I can find again.

Halfkiddio · 05-12-2016, 10:01 AM

From what I remember however, the 4100 series had some pretty substantial reliability issues. They have had issues with the shocks leaking after one season, as well as failures in the design department.

Thats off the top of my head and some quick google searching. I know JRZ's will last 4-5 years with no rebuilds needed, as Sharif has a set on his personal GTR that have yet to leak or go soft since he put them on 4 years ago. He also has the older design that doesn't have bump stops or dust boots.

You won't believe how much bind there is with the stock bushings.

Anyone had any experience with the tein mono flex or other tein? They have a good adjustment range, keep the oem spring location. One of the guys at z1 really likes them on a co workers car and states his stance are too soft but he's going more and more towards track. Makes me a bit worried how firm the tein ride for daily driver crumbling ca roads.

I politely disagree here. I would refrain from making such general statement.

Amount of time is not the determining factor. The combination of type of usage and amount of miles determine needs for servicing/rebuilding. None of the high end stuff, if really being used, can retain its performance for that long without any servicing.

For the competitive guys, shock rebuilds are part of the game. Oil degrades, shims and seals weaken due to heat and usage, etc, no way around it. However, there have been cases where people don't even feel anything wrong when shock oil had turned into goo. Go figure (not implying sharif).

I like this, there seems to be competition between the JRZ and AST. Much like FI or AAM! HA, can't go wrong either way. I'll be doing more research soon on comparing the two, but all this info has helped tremendously!

Yea I'm still torn. Looks fortune can either do a min 1in drop with Oem spring mount or Oem height with true rear coil overs. AST is true rear coil overs and can reach near Oem height, tein can do min drop with Oem spring perch and linear springs so that sounds great yet from what I have gathered they are harsh. I am warming up to the idea of true coil overs which then would probably lean towards AST. I just don't know why a designer would choose to go true coil over vs the Oem design and risk body damage. Just can't seem to have my cake and eat it too.

Oh and vs fi bs Sam I went stillen. Not the most popular but I like it, awsome Oem quiet at cruise and nice not and power at WOT.

I will agree with that. I admit that was a general statement based on one person's experience, but I also know JRZ's will last a long amount of time given the abuse they can receive. They can wear out faster, as it all depends on the specific circumstances of a particular car. Motorsports teams that rebuild them every couple events have the money to support that level of maintenance, but they are also making sure the driver can get every .001 out of a lap. For the normal user, you don't need to worry about that thousandth of a second per lap, so you can go longer in between rebuilds/refreshes.

A proper company would do a ton of R&D on what happens to the chassis when you switch over to the true type coilover before ever releasing them to the public. If their R&D department can't make a failure happen in 300k miles (random number) of rigorous testing, I personally feel that they are perfectly fine for the end users they are targeting.

The Doran team that used 370's in the Continental Tire Challenge use a true type coilover only. Granted, those cars have a cage, but if Nissan directly is okay with using true type coils on a factory-built car, I have no issues doing it to mine.

IIRC Aragosta can be serviced by whoever does ASTs due to shared components, even if the companies aren't "the same." Heck, I think there's even a special rebuild shop at Infineon which isn't too far away from me.

Wow, I ordered my Aragosta Type S directly from Japan through KTS and already have them and will be installing on Monday. I also paid about $1000 less than what Bulletproof had them listed at. Just PM me and I can send you contacts and info. I believe I ordered mine on April 7th.

AST can indeed rebuild these here in the states. All the parts are not 100% the same as what's offered on the AST website. Better or worse? I can't say as I don't have the knowledge to make that determination.

My setup:
