hi all.
just wondering if you could reccomend some bump stops?
i have heard about the fat cat ones but is their site the only place you can get them?
are there any other kits that are known of locally? price??

cheers
Kris

The Fat Cat ones are the same as the Ground Control ones (the 36mm FCM stop is a cut down 56?mm GC one)

Whats do bump stops do?

it gives you more travel for a smoother ride

I run AGX"s with Kings Springs. When I fitted FCM Bumpstops the difference was AMAZING, more consistant handling, far better ride,worth every cent

matty do you still have those bilstein bumpstops?

Huh? That does not make sense. I thought they were rubber things to limit the the level the car bottomed out at?

* Benefits
Gain >1" total bump travel vs. factory 90-97 and 1/2" before bump stop engages (compared to 46mm linear). Lets your stiffer springs do their job!
*Compresses 3 mm less overall vs. 46mm to reduce front tire rubbing - a built-in spacer
*Force increases linearly to ensure predictable handling

that's the one i was looking at before

Interesting... FCM have changed their line up. They used to recommend their 54mm bump stop for NA's with stock ride hight, and the 46mm for lowered springs.

yeah they sound the goods.
...can you get them in australia?

what about the ground control ones?
anything at all available local?

That's all they do on most cars but they do a bit more work in an MX5, especially in an NA. Due to the short suspension travel in the MX5 the gurus at Mazda used the bump stops to aid in upping the spring rate near the end of the suspension travel. Changing the bump stops can change the amount of travel and the spring rate and therefore the ride.

Cool. From the pictures I can see the stops are shaped to 'assist' the spring.

I would not bother with different bump stops and sort out the actual problem, which is the suspension travel reduction when lowering the car. If you are hitting the bump stops a lot than you need to change the top mounts.

On my car, sorting out the top mounts = 1.5 seconds over a 2km sprint track

The idea is to give 20mm more strut travel = 35mm more wheel travel. My mounts are apexi with koni dampers, I had to get some bushes made (see above) Flyin Miata do them too. I re-used the standard bump stops, the car is totally different, no more bouncing around and unpredictability.

Si.

thats the info i want!!!

i think i'll order a pair of these and some of their bump stops for the front in the next couple of weeks!

there was a pair of apexi's for sale on here/ebay a little while ago and i should have snapped them up then.

flying miata are USA yeah??... all orders from there?

thanks again for that Si.G!!!
