Great info Charles.
You're right, it's a very difficult thing to explain to someone when you get good coil-overs on a car. My summation of the difference is that it takes our cars (BMW 3-series) and goes from a sport sedan/coupe to a sports car. The utter control over body motion, suspension reaction time and how quickly the car settles over any kind of road imperfection is mind blowing. You know from yourself the first time you drove my car. It's just so flat and hooks so hard and doesn't let go. BTW: You're going to LOVE the PSS!

Only reason I went with them was because JRZ and VAC recommended them. I haven't regretted the choice.

Very detailed review OP!
This looks like a great kit. My e90 is my DD, but the stock suspension is horrible so replacement must happen soon. I am done with twin tube stuff(my personal choice) so this Monotube has my interest. Super expensive external canister suspension can go on my other two toys. What does something like this set me back? Any forum sponsors sell these? I would rather give my business to forum sponsors who give contribution. |

Thanks!
Call VAC for a quote but here's the link to the RS1s on their site: http://store.vacmotorsports.com/jrz-...e87-p2732.aspx VAC is a forum sponsor. Mike@VAC is their rep here.

Anyone else? I usually like to see quotes from at least 3 vendors and speak to each before placing my order. Price is not the biggest factor, but customer service is. Had too many experience before going with the best quote but also getting the worst customer service after the purchase! |

We obviously sold a kit to Charles and his feedback is here. We have hands on experience installing dozens of JRZ suspension solutions. fun facts: -our main tech ran JRZ exclusively on his Grand Am race cars. -We run JRZ on our E36 race car which is quite a good performer given it's heft. (esp when driven by Aaron Povoledo) -While in Germany for the PMW Show (where we exhibit) last year, we stopped by JRZ to meet with the brass. Pics here: http://www.e90post.com/forums/showpo...59&postcount=2 -Our track day partner, pro driver Aaron Povoledo can be seen in the awesome JRZ video here. https://www.opentrackdayevents.com Please LMK if you have any questions, I can def help

Thanks Mike for the input and that is a fantastic picture!
He is an AWESOME person and a good percentage of the reason I go to VAC. He personally sets up my car and to say he knows his stuff is an understatement.

What does JRZ do for bumpstops? Do the struts have internal bumpstops like Bilstein?
Charles: Any idea how much of a drop you got up front from using camber plates v. the oe strut mounts?

Regarding ride height - not sure what the camber plates do for that either. Regarding an earlier question you asked about the ride height ... Quote:
I imagine most people will buy the RS1 adjustable ride height version.

[QUOTE=CJ421;12337904]Interesting question about the bumpstops, I'm going to have to ask VAC about that one ...
Regarding ride height - not sure what the camber plates do for that either. Regarding an earlier question you asked about the ride height ... It's actually not because I am using M3 springs; VAC tried 335 springs and it was the same height. The M3 spring isn't any taller, just a tad wider. Apparently the ride height behavior is just how this damper is. I imagine most people will buy the RS1 adjustable ride height version.[/QUOTE] I wouldn't. I think you made the right choice going with a wider diameter spring v. a c/o spring.

FYI car is at VAC now for some upgrades - Michelin PSS (235/265), the ETS 5" intercooler, a brake fluid flush, and VAC's beautiful stud kit!

Good review though. Glad your liking those JRZ's. I think you have a great ride height for a full undertray diffuser system.

All parts are installed now, the intercooler is just beautiful. I'm gonna pick up the car later this week when I'm done work.

Bumpstops: This is a copy/paste from the MAN in Holland.
