Rotoflex telescopic conversion questions

[Straight Six]

I want to fit Koni shocks on my MkII Vitesse. Having rung a supplier it appears that they do not sell Konis for the rear of a roto Vitesse because (quote) 'there is something funny about them, and the kits that are out there are rubbish'.

Does anyone know why konis cannot be fitted to a Vitesse? Having experienced failure of Spax shocks a few months after fitting them to the front of my car I really don't want to go down that route again.

Thanks!

SS,

You don't say who you spoke to, but what do they know?

The TSSC sell a conversion kit, extension arms from the top of the rear diff subframe and a pair of Spaxes.  The system works well - I've had it on my race Vitesse for years, but using Avos.

The problem might be that a shocker with a short throw is required baoiut 80mm AFAICR.  The extensions may be availabvle seprately, not from TSSC but consider the kit: http://www.tssc.org.uk/index.php?option=com_virtuemart&page=shop.browse&category_id=62&Itemid=59

Jigsaw also do a similar kit, in fact Canley do too, I think.

I think there was an issue of kits being sold with Konis that were too long. GT quoted the part number for the correct damper but thats probably been deleted. Canleys are sure to know?

I used to have this type of kit on my GT6, found the limited travel of the shocker a problem and have gone back to the orig. mk2 GT6 shocker mount within the wheelarch.

However as the car now has CV shafts, I may use the chassis mounts as Spit/Herald/GT6 mk1/Vit mk 1 etc.

I was considering this conversion whilst I`m in the middle of the suspension rebuild and converting to CV jointed driveshafts. After having spoken to Dave Pearson at Canleys he intimated that some kits on the market had a shocker in with the incorrect travel, he also said that a well sorted car with lever arms in good condition works well ( We didn`t speak about the racers tho`, only for road use). I`m going to try with the lever arms and see how it goes. If I`m unhappy then maybe I`ll try a conversion kit but do some homework on the correct shockers first. Steve.

I'm using the chassis extension arms (home made copies of the TSSC ones) and std Herald/mk 1 Vit dampers.  Work ok but maybe allow a little too much droop for the health of the rotoflexes.  The latter doesn't matter now with CV joints....  You definitely don't want the GT6 roto ones - they are too long.


I wonder what you would find if you measured and compared the open/closed lengths of the 'equivalent' models of all the respective makes, OE, Armstrong, County, Spax, Koni, AVO, Gaz et al.  Bet there would be some differences   ;D

AVO telescopic (single adjustment) part No. XXXX 110/080 (that's open length 11", travel 80mm) £50 each from Demon Tweeks, prob much less elsewhere but I have the catalogue open.  XXXX is the additional code for diameter/single-doubleadj/bush-sphericals. - see the DT catalogue.  There is a wide range to choose from.
