$35 shipped to the lower 48 states and you can purchase them here

Here is the final version of the bumpstops. Due to it being a poly urathane material bumps are not as harsh. On install there are 2 ways you can do this

1) you can just drill the current hole on the axle bigger and bolt them in
or
2) tap it for a 3/8x16 thread and screw them in.

These bumpstops will give you the MOST travel you can get while giving a better feeling when you do bottom out the rear on big dips especially on lowered 500s. Also you can cut these bumpstops down if you want a little more travel and dont mind the stock tires hitting the liners a little (cutting the first notch up top I would start with and test). You will need to remove oem bumpstops when installing these.

My car on the stock 17x7 abarth wheels and 215 40 17 bfg tires. When cutting the first step up top it would rub the liners a little so on the 205 40 17 the rub would be less.


You will remove your old bumpstops when using my red ones

Heya... the Neu-F springs I got already came with their own bumpstops... so far everything feels magical compared to the ****ty coilovers I had on earlier, and even nicer than stock on the bumps. Do you see any advantage to changing out the Neu-F bumpstops with yours? Also, how much would you charge to pre-tap the bumpstops for me?


I am getting the final version of my rear bumpstops for the fiat 500s. These bumpstops are a Polyurethane material and you will have 2 ways to install them.

1) you can just drill the current hole on the axle bigger and bolt them in
or
2) tap it for a 3/8x16 thread and screw them in.

These bumpstops will give you the MOST travel you can get while giving a much better feeling when you do bottom out the rear on big dips especially on lowered 500s.

I am also working on a cromoly front lower control arm that will save weight and be much stronger than oem.

The rear is just as compression stroke limited as the front. Changing the massive towers of plastic filled rear bumpstops will regain valuable free compression travel and make any lowering spring work even better.

Norcal. How about some details on your proposed rear bumpstops? Height, durometer or spring rate curve? If you can give a similar rate curve as stock but position it about 1.5" lower than stock that would be perfect.

Thanks Ryephile... I'll stand by for NorcalSS's response...and am now keenly interested. Even I can understand what 1.5" more effective travel would do for the ride.... ;-P

Im just increasing travel with a shorter poly stop. Im not altering mounting bracket just giving a option for full amount of travel without rubbing and a much smoother hit when car does bottom out. My car is slammed and does hit the bumpstops a lot but it doesnt break yoor back.

My car is at 23 5/8,from ground to fenderlip in rear on 215 40 17s. Thats almost 3 inches over stock.

once I get these new bumpstops in I need to once again load my car up to make sure there isnt rubbing on big dips. For those on 205 40 17 you will be able to trim down the bumpstop since you can have more travel before tire touches inner plastic fenderwell.

Do the fender walls even matter that much? I've worn through mine in several places already with the 215/40/17 and doing auto-X events....doesn't seem to do any damage to the tires...

appologize for my ignorance here...but how do you drill out the hole? do you have to remove the springs first? Or can you drill from the bottom up? The, you just squeeze these stops through the spring coils, or? Sorry. If there is ANY way I can pay you to pre-thread these stops I will gladly pay you whatever your time is worth to do so! I am hesitant to do any drilling on my car's suspension components... Can you tell how ignorant I am here? :-)

there is a hole already there you just open it to 5/16 and you use a 90 degree drill or you can jack up car and use regular drill. then you can tap it for a 3/8x16 bolt or you can go one step wider on the drill bit and just bolt the bumpstop directly to the axle. The bumpstops come already threaded.

Look at the top of the axle that goes in the center of the spring. Hole is already there.

I just got around to putting these on earlier today and after a short drive I'm thoroughly pleased! the Fortune rear shock that I had was far too short so I was running without the factory bump stops period. Subsequently the ride was brutal when it came to big dips or sharp jolts regardless of speed due to the metal on metal contact and the shock bottoming out. On a side note I'll update the Fortune Auto suspension thread for those interested about the progress with that. In the mean time I've swapped back to the factory shock with the much lowered spring (last time I checked the rear fender was 23" from the ground). In a week or so I'll give an update once I get some more realistic miles on the bump stops. At the moment I'm thinking one or two notches can go, but we'll see. Regardless I'd recommend these as a cheap, easy, fix to anybody with a lowered set up. The hardest part of the install was removing the bottom bolt on the shock so the torsion beam would drop low enough to remove the spring. From there all you have to do it remove the rear perch, which is secured via a 12mm bolt, drill out the hole with a 3/8" bit, and then rebolt the new stops in. I was replacing the rear shocks already so it only made sense to switch these out too. In case anybody was on the fence hopefully this will help out a bit. Included are a couple pictures for reference. First is the new bumpstop, second is the difference between the two, third is the factory perch that gets removed, fourth is the damage said perch did, and finally the car needs MoAr LoW!!1!, haha.

Confused about what that is in your 3rd picture (picture of the spring seat in the axle). Is that a fortune part? It is not stock (or at least, not in the 2012 model!).
Any update on how the bump stops are doing? I have a set but can't decide whether to install them or sell them.

Thanks

Got two sets, put them on two different 500's, totally pleased. I used a step drill to drill out the holes, took maybe 10 seconds each to get the holes big enough to pass the stud thru. I was changing springs anyway, so installation was a snap. It MIGHT be possible to squeeze the new stops between the coils without removing them, but you only have to remove the lower shock bolts to get the springs out anyway, so I would recommend just doing that and avoiding the cussing and skinned knuckles. Now the cars have tons of rear travel. Only tradeoff is that I now need stiffer rear shocks to moderate the travel. Highly recommended product.

Yeah, I am confused by that part as well. Probably part of the coilovers.

I am also guessing that these new bump stops mount to the bottom perches on the torsion bar, not to the top at the underside of the car body where the stock ones mount. At least that is what I see in the pictures. Is that correct?

Sorry I missed this post earlier Tony. I just remeasured the car now that I have the factory shock back in place of the Fortune Auto ones and the car is sitting slightly higher. Both front fenders are sitting at 23.5" high, the driver's rear is 23.5" high, and the passenger rear is 23.75" up. This is on the stock 17" Pirellis still. So far though I've only ever heard it rub once over a rather large pothole. So no complaints from this guy!

Thanks for keeping up on this subject. Let us know if you trim the bumpstops. I have the exact same set up and am thinking about taking one step off. I bottom out on larger bumps, but you are correct that bottoming out with these is nothing like bottoming out on the OEM bumpstops. Much gentler feeling with your design.

NORCAL SS
02-02-2014, 03:07 PM
no i have not. My car rubs the plastic liners on big dips. I could cut out the top of the liners but im sure overtime will wear its way thru. Also if you cut to much in rear where the bumper attaches to the body the steel lip back there will cut into the tire so something else to watch out for.

lammie200
02-02-2014, 03:13 PM
Good to know, thanks. I can definitely live without cutting. I will be watching it though. If I can lose the top step, I think that most of my bottoming out will go away. Next up is a bike hitch for mine. I can recheck things then.

Looking at pics online, there's this huge white cone thing mounted at the top part of the spring with a bumpstop mounted on the end of it, pointing at the ground. I know the new bumpstops get mounted to the torsion bar, but what about that huge cone thing above it?

Hey Chops, when you get the new bump stops the OEM ones get removed.

Once the car is on jack stands and the rear wheels removed, the next step is to remove the top (or bottom) shock bolts and lower the suspension to remove the springs. This will expose the bump stops, then just tug on them in a downward motion and they will come off - they have a rubber cone shape head on the end that fits into a factory mounting hole at the top. Then install your new bump stops in their new location and install everything in reverse order and all will be good.

I hope this general information is useful.

So the white cone part stays, just the old bumpstop gets yanked? That cone looks to be about 4" long or so. I imagine that stays there so the new bumpstop has something to hit against.

Everything comes out including the white cone. All that is left is a hole in the sheet metal. The new bumpstops mount on the torsion bar like you said. They hit the area around the hole that is exposed on the top when you bottom out.

I know this makes me look like a schmuck, but I just want to make sure before I go to install this stuff. I'm not referring to the "cup" so to speak that's part of the body.

This is a better picture I Googled, which of course if from a forum member. So the white part and the brown bumpstop is all one in the same, all one piece? If so, that makes more sense.

The only thing Im not sure of is torquing the front Koni's to 41 foot lbs. The guy that installed them just tightened them down and said its tight enough. Im thinking we should have used a crows foot, torque wrench to get a proper 41 foot lbs. BUT this guy has allot of experence yet I like everything by the book. What are your thoughts
