Early Rally Struts??

[Neunelfer]

Gents,

Does anyone have the specs on the early rally struts? To be more specific; I would like to know how far down the spindles were lowered.

Thanks!

Having got it completely wrong and not noticing the difference between raised and lowered because it has been a long day and I think I need to go a drink some beer. (Thanks Max)

For a typical rally car I would just use standard spindle heights.

Chris, he is asking about lowered spindles = raised ride height.

Thanks guys.

Yes, we're building an off-road car. I was under the impression from one of the threads I saw here that the factory actually lowered the spindles and used the RSR gussets on a rally strut. That's the intent, I could simply "wing it" but, I always like to see what the boys from Stuttgart came up with in the past.

Tuthill does this regularly, I believe.

Tuthill have had some larger than standard front spindles forged some time ago but their latest EXE-TC struts are sold on an exchange basis so I am not sure if they use these parts now.

EXE-TC show a unit with a non-standard spindle on their website so there may be more than one type available - again I think that this forging is supplied by Tuthill.

There are also some billet machined spindles around being supplied by Ex-Skoda Motorsport guys. These use a separate bolt-on steering arm and work with Reiga damper inserts - either 3way of 4 way.

The Historic Safari rally is relatively lax in terms of suspension and for the UK (BHRC) and FIA only conventional dampers without remote cans would be permitted.

All of these cars use post 69 style struts and not the early 65-68 Type legs.

For most events the standard spindle position with the RSR style reinforcement seems perfectly adequate.

This style of reinforcement has been used for years on Cortinas, Escorts and the like and is well proven.

'Off Road' doesn't really explain the duty.

For a typical gravel event such as 1000 Lakes or the UK Forests then ride height will still be relatively low and an increase of maybe 1" from standard.




I was closely involved with the build/development of this car which won the BHRC in 2008. It used a Twin Plug 3.0SC motor we sourced from Henry at Supertec , a gearkit and ratios we developed and manufactured in the UK with a Gripper LSD.

The dampers were Bilstein with 1000 Lakes valving, 19mm front bars, 26mm rears.

On good smooth asphalt (Belgium, Holland, France) it was lowered about 1".

On rough Asphalt (Ireland, Isle of Man) it was raised to about stock ride height.

On gravel it was raised about 1" above stock and the rear sway bar removed.

It didn't do too badly and won the Championship overall.

The shell was significantly strengthened and I do have templates of all of the plates used in the body prep.

The earlier 65-68 strut is quite strong and seems to present few problems.

For very rough events bottom ball joints can fail and have some angle issues. We have drawn, but not had time to make a high angle joint, with a larger diameter shank - hopefully next year.

Thanks Chris. Spectacular stuff.

We're building a vehicle for Utah's backcountry and offroad trails.

Higher clearance will be a must so I was thinking of actually lowering spindles to accommodate the terrain which is very rocky in places. There are hundreds of trails here in Utah to navigate.

This will be a thorough build but make no mistake, it will not be a class built race car. Just for fun but done right.
