Steve - there are 24 clicks available and I understand that you need to set them to full hard and then count the clicks from there. I have set them at 14 clicks from hard as per a suggestion I read which is close to half way. 24 would be fully soft.

I think Arnie could be right - it doesn't feel right although the springs are labelled 150.

I'll try setting them to full soft and see if that makes a difference.

Fitted Nitron dampers at the weekend with 250lbft front and 150lbft rear springs and the ride is now very firm to the point of being uncomfortable for the passenger and making throttle control on bumpy B roads difficult.

The dampers are set at 14 clicks from hard both front and rear, the rear (over the diff) ARB on second softest setting and the front (Freestyle) on softest.

This week I will move the rear ARB to the softest setting and set the rear dampers to their softest but am I likely to see an improvement?

This could have been an expensive mistake as, if I can't improve things, my wife isn't going to want to travel in or drive the car - and I'm not sure I like it that much.

Will the old progressive springs fit the Nitrons or would it be worth moving to a slightly softer rear spring?

How do you other Nitron users get on with them for road use?

Could the rake of the car affect the ride? It wasn't that easy to set and I will probably get it professionally setup as soon as I can.

There is a very noticeable difference between these 2 tyres. I have just swapped from A048R to CR500 and the ride height dropped siginificantly. With adjustable spring platforms this is easily corrected.

If you are using the same size on the rear it will affect the gearing noticeably. I'm not sure how that will translate to feel but it should make the car accelerate more quickly - it will also affect your speedo reading.

I have changed to wider rears and hence the 205/55 CR500 is about the same diameter as the old 185/60 A048R.

1st up a red/ali seven heading towards Aylesbury on A41 and then a bit later on the same road a metallic blue seven. I was in the yellow seven.

See you there - hopefully I'll have had a bit more chance to play with the settings by then. Perhaps I'll try softening the dampers tomorrow or try softening the rear ARB.

The car was certainly well planted today - turn in was very confident - but I need to sort out the harsh rear because on very bumpy roads I found I couldn't control the throttle very well and if I hit a big bump then I ended up kangarooing ☹️

I can see this being a time consuming exercise but I'm sure it will be worth it in the end.

Went for 14 clicks from hard on both but I think the rear could do with being a bit softer. 150lbft rear springs are noticeably "bumpier" than the progressives I've taken off. Hopefully they'll bed in a bit. I have set my adjustable front ARB to the softest setting and I may need to soften the back as well (its on softest but one at the moment)

Guess I get to play with the settings at Llandow next weekend. 😬

I could really do with a professional setup as I found it quite difficult to get the ride heights even all round. I have approximately 15mm rake but it would be nice to have an expert take a look.

Yellow SL #32

No manual on the Nitron site that I can see ☹️.

Another question: what is a good starting point for number of clicks on damper adjustment?

I found a post from Peter that recommending 14 back from hard on the rear but he couldn't remember the value for the fronts.

Yellow SL #32

Thanks Barbara - I'll read the instructions carefully and delay my arrival appropriately. That is of course if I get a place.

Yellow SL #32

Cheers. Thats the way I thought they should go.

Yellow SL #32

Mark - do you mean the damping adjusters? i.e. the blue knurled knob.

Yellow SL #32

My Nitron dampers arrived this morning so looks like I'll be freezing my bits off in the garage over the weekend.

What is the correct orientation to fit them? Spring at top or spring at bottom? I know they can be run "upside down" but what is upside down as there isn't a label for top and bottom ?

Any other fitting tips gratefully received.

Edited to say - opened other box to find bag of spacers 😳.

One of those 48 hour varieties no less .

Yellow SL #32

Code: HSMP73720 - looks like £140 - £160 +VAT but I can't see if that includes the boom microphone. You also need an adaptor which is about £10 + VAT or £35 + VAT for the military spec one.

Code: HSMP73490 - waterproof version of the above but can't find a price.

Looks like a telephone call is required.

for the Halfords Pro ratchet spanners. I got the metric ones with a 3/8" socket set that my wife bought me two Xmases ago, but it was missing a 15mm one which is quite a useful size. So Xmas just gone I asked Santa for the imperial set and the missing 15mm size - she came up trumps again 😬.

The spanners are really well made and have nice small increment on the ratchet that means you can use them easily in confined spaces. The downside is that the ratchet heads are flat where a normal ring spanner head would be angled. I don't find this a problem most of the time, but I have seen ratchet spanners where the head pivots as well allowing more fleixbility.

Mine lasted less than 4000 road miles, a couple of track days and a Dunsfold handling day (mmm...donuts 😬) and were down to the wear bars when I replaced them. You only get (I think) 4mm of tread to start with so it soon goes .

No problem with bellhousing dry sump and no problem with heater either.

I'd do it if I could. Unfortunately have already booked to be away that weekend. Also missing Curborough 2 sprint ☹️.

This company seem to do a fair range, mostly aimed at pilots but they have some lightweight headsets and they do adaptors for Autocom systems.

Yellow SL #32

Fits neatly on the rear bulkhead in the boot between the 2 diagonal chassis memebers. You'll need to run some power to it - I ran new cables (positive fused with inline fuse) down the transmission tunnel and terminated in a 2.4mm power socket. I then wired a 2.4mm jack to the power lead of the Autocom. The headset cables were then fed along the top of the bulhead and through the holes where the inertia reels would have been behind your shoulder. I have seen a very neat solution where the plugs were connected to a socket flush mounted in the bulkhead roughly where your elbows are. The cables for phone and music I ran along the transmission tunnel to terminate where the handbrake is.

I don't believe there is any better solution than the Autocom but some people recommend Starcom as a cheaper alternative. I have not compared the 2 so cannot comment but Autocom, once set up correctly, is excellent. Check the Autocom website for details.

Thanks Mark - had to post the form today so wrote on it that I am entered in the novice championship so hopefully I'll end up in the correct category.

Yellow SL #32

On the Llandow form it says:

A novice is defined as a person holding a Non-Race National B license for the first time in 2006 and taking part in their first competitive season of Motor Speed events.

On the Curborough form it says:

A 'Novice' for the purposes of the 'Novice Awards' is a competitor whom has never taken part in a competitive motor speed event at any location before.

Is the wording on the Curborough form the old wording and should I still tick Novice?

Yellow SL #32

Barbara - I'll be in Class 5.

I have completed my form and the online form so it will be in the post today 😬.

Yellow SL #32

OK - just got to convince my wife! Form is in front of me so I can get it in the post today.

Yellow SL #32

Not trailering so I reckon I can get there in under 2 hours. Means leaving at 6:30 . I'll have a think about it. It's a real bu99er as I can't do the Curborough 2 in August so really wanted to do this one. Annoyed at work for organising something in Sweden on a Friday - don't they know that we have much more important things to do .

Yellow SL #32

What is the latest time I can get to Curborough for in order to sign on , get through scrutineering, etc? I am in Sweden on Friday, returning late, so can't really get to Curborough on Friday night. It's a 2 hours plus drive for me (and I don't do mornings very well 😳) so if I am to try and get a place I need to know that I haven't got to get up in the early hours to get there.
