Does the cruise control still work when the traction control light is on?

SCC are the go-to-guys for spacers IMO. I am pretty sure the <12mm hub centric ones are not a straight fit. But I might be wrong of course. https://spurverbreiterung.de/index.php?cat=c285_Lotus.html&bezeichnung=Exige&typ=3. Gen

5 mm spacers are the generic non-hub centric ones. 10mm spacers (to my knowledge) don't exist for the Exige V6. Starting from 12-13mm you can have hub centric ones.

What was wrong with the valve then?

I'm at 132 dB at 3k rpm at 1m distance 🤔😅 with valve open (but that's on a cheap smartphone app... The calibrated meter only goes up to 130 dBA)... By no means scientific and those apps (and esp. the hardware) suck. But it is REALLY loud (and really quiet with valve closed 👍👍). Best of both worlds.

Agree with Dave, it makes no sense "it would work with dealer software" and then won't work when "standalone", other than being disabled in the settings (if that is even possible, no idea, Dave knows). But, if everything used to work before, it really can only be one (or more) of four things (from likely to less likely) BUT doesn't compute with the "dealer software" thing: - mechanical valve in the exhaust stuck / diaphragm ruptured - electronic solenoid kaput - vacuum line broken/interupted - cabling to solenoid/other kaput. The override is a simple switched 12V+ cable to the OEM solenoid. (works, I have it 😇)

Realised not all pics are linked; so for good measure: Looks good.

@piwo better for what? And oh, welcome!

That's the JUBU one! Nice!

eVenturi stuff are pieces of art!

@Jack Like stated above and confirmed by Dave, the 4xx cars have 60mm Y-piping merging into 76mm going to the S-bend and back box. It is my understanding that the S-bend on 4xx cars is 76mm. On the V6 and 350 (and 380) it's 63mm (and the Y-pipe is 51mm). Edit: just measured: the S-pipe/bend on 4xx car is indeed 76mm. So for 4xx: manifold (51mm?) -> Y-pipe 2x60mm -> 76mm S-bend -> 76mm back box. For 3xx: manifold 51mm -> 2x51mm Y-pipe -> 63mm S-bend-> 63mm back box

@alias23 Whilst Jack being several hours "behind" us, I can answer how it's done on DixieV6's car, as he runs no cats either. The only thing to do is get 2 O2 simulators for the post-cat O2 sensors to trick them in thinking there is still a cat/cats present. Basically you alter the waveform reading of the sensor. This can be done mechanically (like Dixie did); or can be done electronically (needs some limited electronics in parallel over the sensors). This is also a solution when you do have a sport cat but due to its placement further down the exhaust stream compared to OEM doesn't heat up quickly enough to avoid the "P04xx" codes (catalyst efficiency below threshold bank 1 or 2). I know that on some Komotec installations this is done "out of the box" too to avoid the CELs. sorry for OT. On topic: sry, no clue. I thought that 57mm aftermarket was already pretty big (most aftermarket versions for the 3xx cars are 54mm) for the Y-pipes until Lotus brought the 60mm version on the 4xx cars.

That's sorted then! 👍

pipes iced up?

Ah, learnt something new (re no 3 mm spacer on OEM Sport 380 wheels). It's easy then, get a 3 - 5 mm lug centric spacer as they always fit. OR... you have that dealer order you the hubcentric H&R ones, and let us know if they fit; would be very interested to know that. The issue IMO is not the spigot size, it's the lip on that spacer so machining won't do anything, but again, I'm no specialist. In both cases you need longer bolts. Dave? 😉

Honestly, I think those will not fit over the lip on the hub. If you only need 5mm you can go for generic non hub centric spacers with longer bolts. I used to run those on my OEM wheels without any issue. But, hey, I'm not gonna contradict a Lotus dealer 😉 ;-). I'm sure Dave might help you better. Not saying to get new wheels (there already is a 2 or 3 mm spacer on those 380 wheels)... Spacer on spacer... , you know 🙂 Let us know how things go.

As a follow-up question: is that HR spacer then a hubcentric spacer? If so, what is the thickness? DixieV6 on here has spacers custom made and for it to be hubcentric is was 12.5mm IIRC thick as a minimum. So the H&R one will be at least that, I guess 13mm? If it's not hubcentric, it'll be max 5mm or so?

from the previous page of this post: Centre spigot hole diameter Size - Rear 68.14 mm

@Diablos-666 jup, 2 small strips of 3m vhd on mine. Mind that the matte carbon is not protected so you can't polish scratches out like the gloss version. Therefore I had thel wrapped in Xpel Stealth. Looks great!

I have them. What hole are you refering to? If it's the two holes "at the back" they come with, I just used a blanking plug to plug them as they have no use? Just pull hard on the OEM ones, add some padding on the new ones to "under fill" the gap and done. On a side note: they are not a 100% exact fit... (I have the matte ones)

The front and rear screws to my knowledge only adjust the tilting of the window front to back (so the cabin inwards - outwards position); but I am not 100% sure.

Are they SPAL fans? Just wondering. Good job!!

@GoldenGun Looking very good! Remind me to restock on ACF50 ;-). I also notice the gearbox cooler mesh on the undertray is different on your car as on mine, what year is yours? On the sensors: you absolutely need to reinstall these post cat sensors exactly as they came out. (notice the twisted wiring, did you disconnect them before removel to be able to twist the cable whilst undoing?). How's the sound?

I use this tool and I don't bother to undo the screws. I just 'lever' them out and replace with new ones. I just hate them 🙂 https://www.amazon.co.uk/Retainer-Plastic-Rivets-Fasteners-Removal/dp/B0825WTPDH#
