That would be ok for me, if the car is optimised for Brands Indy and Lydden Hill, that's where it will get at least 90% of it's use.
The occasional trip to Snetterton might be a bit painful, but I'd have to live with that.
I'd love to drive Spa but I'd be touring round, I'll never do enough laps...
So I guess on the flip side where I'm bashing the limiter in 3rd at the end of the straight I'll be able to change up to 4th early enough to make it worthwhile. Which also sounds like an improvement.
So taking a current lap around Lydden:
Out of paddock bend in 3rd, hit the limiter at the end...
That sounds like exactly what I need at the moment, along with a stronger clutch.
I guess it would make sense to replace the geabox casing at the same time, so could you give me an idea of cost if I were to send you the original box plus the one with the Gripper Diff.
Also how do you decide on...
Because my brain is incapable of visualising exactly how the gears, ratios, final drive and differentials actually work I will pm you for more detail, costs etc.
But in very basic terms what would that do?
Sorry to be so thick, but no point pretending you understand something when you really don't!
Many thanks for the replies, lots of very useful information there, including that I now know the broken part is called a 'strap'.
The BMW thread was really useful, thanks @clio tyres
I can now visualise that with the flywheel turning the clutch the strap is stretched and would be very strong...
So the clutch cover is broken again, but this time one of the 3 'leaf springs' riveted to the cover and pressure plate has gone.
Firstly, this new hole in the housing suggested something was wrong!
Inside the housing some scoring:
All 6 clutch cover bolts were tight but you can see at '5...
I was looking at the Clarke cranes, but a bit dearer when added delivery etc. Almost tempted as Clarke is a bit more of a 'name' than SGS. I went for SGS on the basis that I'm not a mechanic, and it's not going to get much use, but tbh I can't see how you'd get anything more solid and...
The new toy has arrived. Seems really good quality, almost old fashioned heavyweight engineering,
Loads of weight for your money, but no assembly instructions. But I suppose if you need them you shouldn't really be using it.
Good fun asembling it, like a giant meccano set.
Thought I'd at...
I started to take things apart in anticipation of the arrival of the engine crane.
Things went quite well, so pretty much have everything disconnected or removed, just the upper engine and gearbox mounts remaining,
I've removed quite a bit of stuff to get more room, such as radiator/fan, the...
Is the A052 the replacement for A048? That's what I was thinking of seeing other racers use last year.
Looks like a completely different tread pattern.
No it's a fairly open series, so 15's might be a good option to give a lot more tyre choice, particularly as @robzracing says there might be an option for part worn slicks.
At 8kg/mm all round the springs are probably a bit soft, but I can easily get harder springs.
The A052 are used by quite a...
Many thanks for the information. I was a bit concerned about flex going from 45 to 50 profile as well, so I will definitely avoid them.
Sadly Federal RS-RR don't appear to be made in 16" anyway.
I would do at Brands Hatch and I really want to try the ar-1, but unfortunately Lydden is so abrasive it will destroy a softish compound in a single trackday.
I did heat cycle a pair of the Zestinhos which made them last a bit better, but they would never last a second trackday.
A pair of ar-1...
I have a Clio 182 track/race car, still with the OEM 16" wheels and using 205 16 45 tyres
I've had decent laptimes on the old Federal RSR-R tyres.
I've had not so good laptimes and shocking wet performance on the Yoko Advan NeovaAD08RS (probably the worst performance track tyre I've ever used)...
Thanks for the reply
I did consider the location of the end of the gearbox shaft, but from the diagram below taken from the 182 workshop manual I came to the conclusion that the end of the shaft doesn't locate in a bearing, it just sits in thin air. Is that possible or likely?
What would be...
True it does look like the bearing is alreadly pushing the springs in, which corrresponds with the fork angle being back towards the gearbox.
But if you take the cable off the fork, the springs don't push the bearing back.
And if you depress the clutch the fork travel is still c.30mm
So it looks...
Good spot, hadn't noticed that. Nothing's running but each time the clutch is depressed it looks it spits a bit of crap out of the cover.
The car's been stationary for a week, but I can't see how anything could fall in there, so have to assume its a bit of component!
Can't see it happeneing when...
Good visual of what happens both with and without engine running there @Touring_Rob
So I thought I'd make my own, and I can't see anything wrong with the what's happening!
Can't see any swarf or hear any grinding.
The springs seem to move plenty.....maybe too much????
Can anyone with a more...
Hi, did you sprint at Lydden back when TWMC had sprints in the morning and SEMSEC had races in the afternoon on a Saturday? If so we've probably been there on the same day. I started racing there in 2012 in my Impreza, great fun and very laid back compared to other clubs and venues.
Definitely...
Many thanks for the feedback, I'm going to go for it!
Looking at the cost of engine crane hire I might as well buy an SGS crane and leveller ( then I'll have it for when I build my own race engine🤣 )
I think I'm ok for belts and accessories, Cam belt about 2000miles, alternator, pas pump and...
Been doing some actual work these past couple of days, so haven't done anything about the clutch yet.
I guess I must have got the correct flywheel, but will contact PMS on Monday regarding the thickness.
I am seriously considering lifting the engine and geabox out this time, rather than doing...
Can't find the PMS invoice for the flywheel, which is odd as I have kept all other invoices for engine mounts, camber shims etc! Typical.
I think I had it delvered straight to the garage which would explain that.
99% sure it was standard as I recall telephoning before ordereing it, but I will...
Unfortunately I don't have the original flywheel, must have gone in the garage scrap bin!
I'll see if I can find the specs for OEM.
Though I'm thinking if Pure Motorsport sell a lot of these it would be more of a common issue though!
Once I've got the thing out and confirmed that it's a release...
OUCH! But there's something in that. I'm no Aryton Schuhamilton who can do 15 different driving tasks exceptionally well whilst composing an aria.
I do aim to drive with mechanical sympathy, but spotting the braking point, hitting it, braking just enough while changing down, spotting the apex...
Just the flywheel, no cable, but also to note this was when the gripper diff was fitted.
So in a nutshell I was running 128,000 mile clutch on original flywheel and gearbox and getting really frustrated with the lack of drive out the corners, having previously been pampered in a 4WD, tricky diff...
My problem with heel and toe is very much like left foot braking, I practice and it's all great. Then I get on track and it all goes to pot!
Also I have tiny feet, no excuse, but I could do with a little extension peg on the trottle pedal, is such a thing available of the shelf? I ended up...
