Conversion to abarth suspension problem HELP PLEASE !
Posted: April 6th, 2010, 3:34 pm
Guys
As some you you know I am currently working on my rear suspension trying t install an original Abarth setup.
In standard 131 suspension the springs are supported by the rear axis/diff assembly. On the Abart the strut bodies are bolted to the rear hub and the springs are supported by adjusting rings in the strut body . This moves the spring upwards. The problem is that on standard 131 the top spring support is a neck (for lack of a proper word) welded in the turret at the wheel arch level. Proper length spring will not fit not this distance and a smallest diameter spring ( big enough for the strut bodies) fits too tight into this neck.
Change one : Th neck has to be cut off to provide wider opening for the spring ( as well as to be wide enough to allow installation of a standard front strut mount - see below) .
The second problem is the rear top strut mount. On standard 131 this element is fitted from the top and far from strong enough to withstand the forces involved in absorption or shocks developed by the suspension of a driving car. In the modified version it has to be supported by a top strut mount which is installed from underneath and will be strong enough to hold the rear suspension Thus this has to be changed .
Change two : the standard top mount has to be strengthened. I plan to put a front strut mount ( installed from underneath to support the spring as well as bold in the strut.
Anybody has any experience or ideas on this type of modification ?
I therefore need the part that goes on top of front shock and bolts to the body front underneath the turret.
An the top cup washer that goes on top under the nut.
I now there is a another type of this mounting (type 2)
These could also be used ( I think ) provided he neck of type 2 will fit onto the top turret opening of 70 mm and the bolt opening on top is large enough to accommodate a nut and a wrench I must use to bolt the shock.
Actually these may be even better , provided :
1/ the distance between the bolts is 90 mm and not 95 as in type 1
2 / the largest diameter of the bottom part is smaller than 130mm .
Does anybody know the measurements and or has any of these parts sapre ? ]
