Title: Series 1 lower wishbones
Post by: rodney3010 on 08 February, 2011, 04:11:25 PM
Its been recommended to me to replace my series 3 coupe lower wishbones with those from series 1 as this will affect the camber. Has anyone had any experience of this, if so is it a worthwhile mod? If it effects the decision I may in the short term be using the wheels from a 2000HF.

Only the 1600 cars had negative camber front suspension, and in that regard it doesn't matter if you use S1 or S2 wishbones. The change to negative camber on the 1600 is achieved by lengthening the bottom wishbone and shortening the top. So it's eminently doable (if expensive, probably cost 500+ to get a set). It will effect the steering feel making it heavier, if sharper if that's what you want.

Don't forget that the steering box on a 1600HF is also different, so if you want to get the feel of a 1600HF you will need to change everything.

HF2000 flavia wheels will fit without changing.

The lower arms are easier to change than the top so you can get some change in camber if you fit HF bottom wishbones. But I would fit both HF (good luck with changing the uppers) wishbones. You will need S1 upper mountings as the S2/S3 had metalastic if I remember.

If you buy modded arms make sure they are from an expert welder with jig such as Omicron (hence the price))

John Day modified my s3 hillclimb/track coupe wishbones ,[details of which are in a previous thread]with good results.no more understeer.just move the 'holes' in the uppers and extend the lowers.i know some modifiers only recommend extending the lowers but i remember Johns mod as being the single most effective one in the handling dept so i wont question his wisdom[many thanks John for your help over the last 23?years].probably a mornings work on the bench=50 quid around here at the local welders/fabricators if you can supervise the work[or in the jig]which would not be difficult to make if a pair of neg. camber items are to hand as patterns.best regards richard

My Fulvia Zagato was modified by the previous owner to have the HF wishbones and the negative camber. It seems a welldone job. Honestly I don't feel any obvious difference from my standard S2 coupe, maybe I am not a very good driver? Andrea

the handling improvement was most noticable  at the circuits at speeds unsuitable for the corners of public roads.i now have positive camber on my current cars which i find fine for my road driving these days.also i seem to remember that lowering the front ride height affected wheel camber-lowering producing more positive camber?the arms modded by John took into consideration   my existing lower ride height whereas the production HF original equipment items are of  dimensions to match the standard HF rideheight.best regards richard
