it will make a huge difference! and be a great suspension mod... you will be very happy !

 

I agree "Latte"

I have extensive mods and most to enhance handling and stability.

Please let me know if it makes a difference after installation...or if it is a "Placebo" effect. mentally you might feel that it helps.

 

I'll make every effort to be as objective as I can.

The wait is killing me, though - I won't be able to put it on until this Sunday.

 

i'm also installing my USS this weekend. i would like to hear any advice on installing the nut inserts from those of you who have already done it. thanks in advence.

 

Be patient.
Don't make the holes too big ... lightly tap the insert into the hole with a small hammer.
Tighten it up with the tool provided.

Don't worry, it's really easy.

 

That is a good point. Be sure to use the drill bit provided to just barely make the hole bigger. Once the bit passes thru go for the insert install.

I think I may have a problem, perhaps over-enlarging the hole. I had my car on jackstands, and the drill I was using didn't clear the ground, so I had to drill at a slight angle. After using the nut-insert tool and "crushing" the nut, the nut still falls out. I let the drill bit pass through, and nudged it out with the drill in reverse (I felt that the hole was still sufficiently small because the bit wouldn't come out with mere tugging). I'm feeling quite stupid right now. Any advice regarding how to best proceed would be appreciated. I think part of the problem is the insulating material doesn't allow the nut to sit flush against the bottom of the car, similar to what FlynHawaiian stated.

What is considered over-torquing? I don't have a 8mm hex bit for a drill, so I was just hand-torquing with a normal hand-held allen key. Nonetheless, I managed to crush the crushable part of the nut insert completely - is that too much?

On the bright side, the back and middle braces are already noticeably holding the car together better. Over bumps, the ride is not longer jarring, and corners definitely feel flatter. I can't wait to resolve the issue with the front brace nuts for the full synergetic effect of the USS.

 

definately tightens things up! also adds a tiny bit of oversteer to the car. i was lucky enough to have use of a lift this weekend and installed my USS. it went right on with no issues whatsoever. there were no problems with the inserts or passenger side bolts. it's a beautiful piece and performs up to it's claims.

 

Since I was able to get my jury duty postponed, and its raining so I can't work anyway. I'm going to install mine today.

 

Are you sure you expanded the insert completely? If the hole was too large the insert would just rotate around in the hole without expanding the crushable area.

 

Absolutely - there is no more material remaining on the insert to be crushed/expanded.

I'm tempted to try some epoxy to hold the nut inserts in place at this juncture.

 

You might want to see if you can find larger inserts first? I would phone Peter and ask what he recommends.

 

I was just made aware of the issue with the pulled out nutinsert.
The reallity is that if the car is put up on a lift and the nutinsert is attached
with a air impact gun, expanding the insert faster then possible by hand.
This will most likely fix the problem.**

So the moral of the story......keep the drill straight so you won't elongate the
hole.

**If not, don't call me before 9:30am pst.

Thank you for the advice, sir!

I had an inkling that it might help to have an electric/air impact gun while I was torquing down the insert, but it was next to impossible to find a 8mm hex bit for that specific application. Finally managed to locate one earlier tonight. Hopefully it'll work out and won't require drastic action.

Edit: I had to swing by Bay Bridge Motors briefly for a quick inspection on another part, and they had the time to put my car on a lift and install the nut insert properly. I haven't had the opportunity to do any aggressive runs since to test out the USS yet.

 

Just ordered mine through WorldOne. Can't wait to get it installed.....car is stock except for some Goodyear F1's, Milltek and Dinan airbox.

 

So? Does it add understeer or oversteer. Both have been mentioned here.

 

When we first put the system on we expected there to be a bit more understeer in slower tight corners. When I actually made it to the track I thought there was perhaps a bit more than without the USS but when Will Turner drove the car he thought there was almost no understeer at all. I went out with him for a lap session and saw that with his driving style there actually was none. He was able to rotate the car at will in the same corners I was trying to carve thru. When using his method I can safely say that there is VERY little understeer if any at all.

Thanks.
Since I'm not sure of the specs of the car you were testing on could you mention what other mods there were?
Here's my curiosity.
I added the OMP frame brace and like the effect it had on ride quality and chassis stiffness. Ironically a number of people here thought it was a waste of money and would make no difference.
I have only a 22mm rear bar on soft and an otherwise stock suspension.
The OMP definitely added understeer. Not much but it's there.

Your references may be about a car that is already more neutral than mine due to other suspension mods so I'm trying to gauge the impact your system may have on my car.
Again thanks

 

Lets see if i can remember what was on it at the time.
H-sport front and rear competition bars. Rear on middle setting, front on softest. LEDA coilovers with about a 1.3 inch drop. BMP top strut tower brace, Univeda rear upper strut tower brace, SAC front camber plates set to -2 degree , SAC rear adjustable lower control arms set to -1.25 degree. The wheels and tires were Ro'Ja lt5 17/7 with Toyo Ra1 205/40 /17.
I think that is the majority of the handling related items .
I have since put a few thousand miles up in the hills with the car and have been very pleased with that type of driving as well. If you want to PM some of the other people who have installed the USS and see how they are doing. There will be another large group for you to send inquires to shortly as we are shipping out another 30 sets as we speak. Feel free to ask anything else and thanks for the interest.

Thanks for taking the time to answer. Well set up suspension.
Interesting piece of kit.

 

How does this affect the ride otherwise? I get that it improves handling in "spirited" driving but how about the day-to-day stuff? I'd like to improve performance (no track for me, just fun driving around town), but not at the expense of a decent ride. I know the car is not a sedan, but on the other hand I don't want to take my wife for a night out and have her complain about how uncomfortable the ride is.

Thanks,

Paul

 

I can speak for my experience with the OMP bar. My guess is that the USS would have much the same impact.

The car actually rides better. The suspension does more work and the chassis flexes less.
For me alone that was nice. The improved handling is a plus.

 

I've found the the M7 USS eliminates a lot of the chatter I previously had driving over rough surfaces, especially in corners under normal driving conditions as well as more spirited driving. So, IMHO I'd have to say it improves the ride quality overall no matter how you plan to drive your car.

 

Great...how about the warranty? Will this affect the warranty? I'd like to go a few more miles than my current 400 before voiding it

Thanks!

Paul
