Protech Shocks

Looking to order some Protech shocks for a widetrack De Dion S3 project. Duratec motor. Mostly road, but occasional track. What spring rates have people spec’d on their Protechs, please?

Last car was a narrow-track, bike-engined, live-axled 7, so chalk and cheese!

Thanks!

I bought mine through ProComp Motorsport in Birmingham. They advised on the spring ratings for my touring needs in an SV. They also revalved the Protech dampers to suit the Caterham.

Mines not a widetrack, but I've got Protech shocks (single adjusters) on a 1400 Supersport and I went for 250 fronts, 150 rears spring rates for mainly road  use - these replaced 300 fronts and 200 rears which I found a bit hard for road use

Kind regards

What sort of money are we talking for a set of four ProTech spring and damper set ups?

 

Thanks,

David

I paid £576 for 4 springs and dampers including delivery. Bought from ProComp Motorsport.

Blimey Ian, that seems good value. Not much more money than having my billies refurbished, though I guess the ProTech aren't adjustable platforms?

......and go for the spherical bearing (Rose Joint) version too.

Make sure you give Kevin the correct details re the Dedion open length, which is influenced by the lower mount mount location either thro or under the tube,

 

springs Front 225 / 250      Rear 130 / 150

Would you go 225/130 for a road-focussed Duratec?

Also, do you know the appropriate spring lengths and open-damper lengths for a post-96 widetrack with the "under-the-tube" DD pickup point, please?

Is the spherical bearing option OK for the road?

I ran 250 / 150

I'm no racing snake and there are some nasty cats eyes on the roads over here to, if your running wet sump I would certianly go 250 on the front.

I ran with the orange front ARB and no rear ARB

Rose joint no problem it rids the suspension of the parasitic stiction inherent with the bush set up.......

Cant check the lengths up front as I'm now Freestyle inboard....
