Sam, Found a note from Mark... The problem was found by Dan at https://www.hpeauto.co.uk/ It's possible that the problem you have is not the same but worth a try....

Sam, I think the fix was just some minor matching of the bushes... I'm assuming it's a manufacturing fault that was only on some bushes. I think we're only talking about a thou or two... I'll send you Marks contact details via PM tomorrow. Andy

Well it's hard to say that the handling is much better as I've only managed to do about 50 miles since fitting. But, yes it feels like it is to me and I can easily tweek things how I want. BUT... the guy I sold them too discovered what the problem is! Apparently it's the bushes that are at fault... I don't know the details but I can put you in touch with him if you want.... IIRC the wrong size allows the shock to move in the Bush and then it knocks. Andy

looking at this photo of a 360 there's no canister on the bar ...

As an update... @tomprout I have now fitted 3 ways to the car and have to say they are just perfect. No bangs or knocks or anything unexpected. Very happy bunny ! So far the handling seems exactly the same but don't want to drive it far until it's been in for a full geo. These ones are factory spec Cupsports with 500/850 springs (road spec rather than the factory 550/1100)

For what it's worth .... this is the 350 airbox seems to be more domed than the 410 And you can just see the canister attached to the harness bar. quite different to the 410. Might have to be a move to the @alias23 air filter mod .... I wonder how that would affect my warranty ?

@Bandit Thanks ... off side looks exactly the same .... just slightly awkward. Nearside is different ... Airboxes are completely different ... i'll post a photo or two when i get home. I'll have to have a chat with BackOnTrack or Analogue to see what they normally do.

I've just fitted a new set of 3 ways onto my 350 sport. On the factory cars how do you access the canisters to adjust them ? Offside is accessible (a bit awkward) but the near side one is blocked off by the airbox and coolant (?) header. Are the cup etc cars different ? Anyone able to send a photo of the way it's set up ?

Not totally ...... I had them rebuilt by Nitron (FOC) and they are quieter but still make some noise under specific circumstances (smallish pot holes). I'm currently awaiting for a new set of 3 ways, as I'm craving a bit more adjust-ability than the 1 ways can provide. (and everyone tells me they are quieter too) Anyone want a cheap set of NTR 46 one way adjustables (550/1100)

Any one going to the event this weekend ? Taking your cars ? https://www.brooklandsmuseum.com/whats-on/supercar-day

I'm going to spend some time this weekend playing with my pressures as i feel the car on Nitrons feels much too "floaty". I was wondering what others are running ? Currently i'm running 28/32 with Nitron suspension and std Pirelli Corsa's

@RedViper Do you find that changing the settings on the shocks makes any difference ? ie quieter on "Soft", noiser on "hard" ? Do you think is gets quieter as they "warm up" ? Just interested in your observations, so far. For reference, if it wasn't for the noise I'd be very happy, the car feels like it's on rails.

Thanks Bibs.... i've already made contact, just waiting for a call back

Thanks for the feedback ... i'm going to go have a chat with the nice people at Back on Track for a professional opinion.

Seriously? Happy to accept that there is more road noise but this sounds like some is hitting the chassis with a hammer. If this is normal, they can have them back...
