Long leave mushrooms racing :-)

[Mike (Cliffie)]

Finally got a day to myself and thought I would give the little monster some badly needed TLC.

 

As the car will be running out on Friday with Lotus on Track it made sense to have a geo and everything checked out. Well thanks to Chris_UK who stood in admirably last week to get the car over to Ollie at Phoenix Motorsport as I was stuck at work. Drama ensued of course; the car handled really badly on a half season old full race geo with a few worn out bearings, the wiper motor gave up the ghost and the tensioner actually destroyed itself.

 

Chris again did a magnificent job getting it there and back although he did say it was the scariest thing he had ever done and made his car almost German in its luxury.

 

This kinda prompted me to get on and get the car back from the race focus and make it more of a track day toy.

 

So out came the race poly windows and back in went the wind up windows and full door furniture as well as the steering column shroud.

 

Thanks to Zoobeef, it has a pair of floormats as well; maybe I may even look at a roof liner???

 

Looking forward to Friday now.

Roof liner eh... Where you gonna get one of them from If you do mean one of the ones I do, I shall find someone who can add "Mike Cantelo "Time Attack Champion 2012 & 2013" If you'd like?

Hey Mike, was the scary bit because of the worn bearings or mostly because of the aggressive geo setting, do you run a lot of toe out at the front?

 

Im hoping to get over to Ollie with mine in the next couple of weeks so he can point out all the bits I did wrong.

 

You taking it back to being a weekend road toy, or just spend each weekend flying around croft with it?

come again?

 

how is an aggressive (whatever that means?) geo going to wear out a bearing?

He mentioned its got worn bearings and the ride on the road when his friend drove it and I wondered if his geo had any effect on the feeling. Ie loads of toe out on front, not much toe in at the back etc

[Scuffers]

that makes even less sense.

 

if a bearing has slack on it, then no geo is going to make much odds, as 1-2mm of toe will be insignificant in the slack a worn bearing will have.

 

bearings wear out usually because of contamination as opposed to just wear, as in they get crap in them (water/salt/etc) this is usually worse for track cars that are used infrequently but then they are used get hot.

 

loads and mileage do not seem to be a factor so much as age and environment.

 

 

[turbotoaster]

Hi simon. I think you miss understood me. I know geo has no effect on bearing wear. What I was asking was, was the bearings the reason for the scary driving only or was his race geo the partial cause of the scaryness

[Mike (Cliffie)]

The ride on the road is scary as the car has a race geo and any bump or deviation in road surface really upsets the car. This was magnified by a completely shot track rod end. The Geo and wear are not related.

 

Bearings wear, they are a service part and mine lasted me four years, two of which were racing so I am well pleased with that.

Let me explain..

1 rose joint was utterly shot, moving about all over the place, this wasnt helped with how they were fitted either.. But thats been resolved now and will post some pics in a bit.. The other one had the split pin snap so the rose joint had started to unwind itself a new split pin and it was as good as new but we replaced it with a new one anyway and kept the old for spare.

The scarey part was this..

350bhp in 850kg with just legal semi slicks in the pissing down rain with lights which pointed to the floor so couldnt see more than 2/3 white lines infront of me.. Then the windscreen wiper packed in twice! Because the front wheels were steering independantly of each other And the steering wheel not centred coupled with a very aggressive track geo it wasnt do much if the back end steps out it was more if it does i cant even try correct it and will end up in a bush..

That was litterally the single most frightening thing ive ever done on 4 wheels, if id of known how bad it was prior to getting in id of probably not bothered..



Rather than using washers we made a propper spacer and conical spacer



This was the geo which id driven down on.

[siztenboots]

toe-in all round

[chris_uk]

toe-in all round

Thats what it was when i first put it on the ramps.. The new geo is much different.

[turbotoaster]

im guessing the reason the camber is more on the right than the left and also alot more on the front was what you ended up with from following the pirometer tyre readings on track, as thats alot more front camber than I thought you would be running.

 

Can you tell us what you reset everything to as it would be interesting for me to know to help me get a baseline to work from on my car.

[LY_Scott]

Holy front camber batman

[Scuffers]

looking at that, I can only assume the ride heights were somewhat different than it was originally set at.

 

rest of it looks about right to be honest (for what it was originally set at).

 

 

 

 

[chris_uk]

Ride heights were raised 10mm all round to what it was then we re-did everything.. Question tho scuffs, why was it set to toe-in ? Rather than toe-out?

if your on about the front, it was not.

 

hence my point about ride heights (although 10mm is not enough of a change to do that).

 

(it was originally set to just toe out from parallel - within the bounds of practical measurement and suspension play)

[2deano5]

didn't we re-do the geo at Brands?
