Title: rear shock absorbers strap limitation
Post by: wolfswest on February 14, 2008, 15:18:30 pm
Somebody advised me to install some sort of straps on the rear-shock absorbers to prevent negative camber on the rear wheels when braking or when you stop pushing the right pedal…  :D
Does somebody has experience with these tools on a street car, positive or negative remarks?

If you don’t know what I’m talking about, here is a picture a “stole” from a dutch forum.  Thx to MartijnC!

  Hello,
 Firstly the straps limit positive camber when you lift on the big end the rear end wants to unload causing the contact patch between tire and road to become smaller this can cause loss of control and often times flips. Most run 12" or 13" straps. Hope this helps.

I have been thinking about purchasing a camber compensator or limit straps for my beetle. How do these straps react in turns and normal driving? Who has experience with a camber compensator?? Thanks

That is what I mean, but difficult to explain in an other language...  But what happens when you brake very hard?

On the Strip, with Slicks, braking hard, you will most surely end up on the Roof... ;)

Even if I think that 13" will be OK,Well you first have to check with a jack when your car begin to get a positiv camber then you can determine your lenght!
Using flop stop is also a good and simple solution

Can somebody give me more info on the "flop stops"  or other solutions?  I want to make my car more safe when I loose my foot of the trottle @ high speeds...

I used the Bugpack "flop stops" on my race car - just a simple bracket that bolts to the bottom oedge of the springplate. Purpose is, as said above, to stop the wheels tucking under when coming off the throttle. I made som enquiries about using them on the street and was told it wasn't a good idea as for street driving you are effectively limiting the suspension in one direction and over bumps, potholes etc the car ends up dropping into holes rather than the suspension doing its job. The person said that it was the most scared they had been in their car! :o

OK, not a good idea to use these things on a streetcar...  :-\  mmm

If you use them on the strip they're a really good idea, just take them off before you drive home! If you've got the rear wheels off for changing slicks back to street tyres, you could undo them then!  ;)

  I run 13" straps on my car at all times on the street or strip. It doesn't completely take away down travel just lilmits it hence the name limiting straps. A little positive camber is ok just not the excessive amounts you get with stock suspension. My oppinion. If I jack my car off the ground the spring plate is a little over 1/4" from the perch.

jason, if I understand you correctly you made your straps a little bit longer then the shocks when they are under the car...  I'm a correct?

that is correct I have a small amount of uptravel if the car is lifted with a jack.
