CF front indicator pods sold.

Not sure what the temp is doing - that is precisely the point - how can there be a car of this Duratec power output without the oil temp monitor??

Looks like the front indicator pods are going, set of wheels and 2x carbon fibre SV nose cone chin still available.

With regards to the drive shaft - having been dealing with this recently on another car (CSR 175 EU4 spec) after quite lengthy conversation with CC we ended up using 620 SV prop as the one above is in reality an S3 prop wrongly labelled as SV&CSR. https://caterhamparts.co.uk/propshaft/6176-sadev-sv-ford-propshaft.html?search_query=propshaft+CSR&results=382

the only drawback of CSR IRS arrangement is the lack of rear anti roll bar. Irrelevant on the road, excessive lean on the track.

propshaft and driveshafts are diff specific - they would have to be changed with the diff..

James - of course. Hold on.

Re 100 mentioning the mod of the tear drop cover - I'm intersted.

carbon fibre stuff added

Well, it turns on at some point.

Sorry about that, I was reacting to some other posts describing an impending diff catastrophe. you might be right about the alternatives for the BMW diff, my car still uses 7" Sierra.

Mine is about 60-70'C. might be the budget gauge..

When the preload spring breaks, the diff will stop locking. The car struggles to exit the corners properly on the race track and you can't steer it with your right foot. When you jack the rear up and spin the wheel, the other rotates the other way. the reason the preload spring breaks is metal fatigue as it is pressed flat every time the diff locks. there are products on the market that don't do this.

Buy proper diffs. Titan is - not the best. There is a reason the pre-load spring is breaking down...

Same as mine. Those Ferodos were standard for quite a long time.

Hold on, do you have uprated four pot calipers?

Hi James, this is what mine had - albeit 2014 built. https://caterhamparts.co.uk/brake-pads/348-brake-pads-4-pot-calipers-roadtrack.html

Had a look at it yesterday - the coolant inlet comes in between the supercharger inlet and the plenum chamber inlet - not much space left. Lack of space is the primary reason the plastic thermostat housing does not fit. the solution in my opinion it to modify the billet aluminium flange by adding another pipe inlet (16mm) for the header tank to connect into. Aligning the new pipe inlet with the thermostat bypass would allow the header tank to be in permanent flow circuit. This would then free up the bypass inlet on the block for its intended purpose - for the bypass hose coming back from the cylinder head. Job done. Another temperature management issue is the lack of oil temp measurement on 620R - this is criminal. I'm in the process of sorting it out. One more addition I would consider is coolant/oil heat exchanger to help with quicker oil warm up - 10W-60 causes oil pressure to run at 65lb/inch2 when cold falling to 30 when warmed up. This could either be a stand alone unit or incorporated into the oil filter housing.

SV front anti roll bar added.

I might help with that as well, mind you, mine is an SV.

It will be T-ed into it.
