Hi Ivorbiota, You mention rear shocks, I remember my first Biota had shocks from a Greaves trial bike, Which sounds about right as where the cars where made at the time there where many British motor cycle part suppliers especially down the road in Darnall.and Attercliffe.

So was the kit made in Derbyshire/Yorkishire ?

If so, never knew that there were any local kit makers

The ones on my first Biota were Girling units intended for a BSA A50 or A65!

 

Not sure yet what is fitted to my current one, definitely a higher spring rate as it hardly moves when you get in, unlike the first one.

Interesting, my first one was quite solid on rear suspension, and was super on grip and cornering, not soft at all, But good handling. What reg was your first . and does it still exist?.

I'm just thinking this one is too solid. Just as yours the handling, roadholding of my first one was brilliant. Never once did the rear end step out of line despite my best efforts. Haven't had chance to try anything with the current one yet, it will have to wait till I get it on a circuit.

 

My first one was DFD697K and it is currently roadgoing. http://biota.jouwweb.nl/articles/ckc

My reconfigured cooling system with purpose made thermostat housing and swirlpot header tank.

The thermostat housing was designed to fit under the bonnet profile. My first Biota had a triangular plate with right-angled pipe sprouting from it pointing backwards - no thermostat. I wanted to go one better.

Update time.

 

I have now replaced the primary gear oil seal to stop this from happening again.

 

20170124_113005_zpsuhe5cfda.jpg

 

I also replaced both driveshaft oil seals and the rubber UJs with Minispares Quinton Hazel roller type. Still getting oil on the garage floor though!

 

It was now ready for its MOT, which it passed. Big thank you to the guys at Southwell Autocentre Ltd.

 

Next stop the MK1 Action Day at Blyton Park

 

However MrsBiota wasn't happy with the state of the seats..

 

IMG_2727r_zpsu1uejegr.jpg

 

..and decided some custom seat covers were needed. We had visited Europa Specialist Spares to look at some Intratrim seats but they wouldn't be delivered in time.

 

So out came some old curtains we had been using as dust sheets and:

Trouble is the important one is missing!

Here it is undergoing some stringent quality control testing by the mistress of the house.

All was well and here we are on track at Blyton

That is another car that I wanted when I was a young and impoverished student. I remember sending off for the manufacturers literature, and was seriously impressed. There can't be many of those still around.

Have lots of fun!
