That's a motorsport-spec mount - tie wraps are lighter than aluminium and rubber!

I will say they can be dusty sometimes though, although unlike the Ferodo stuff which seems to try it's best to eat into your wheels, it tends to just rinse off.

1144's are fine as a daily pad, they bite well even from cold in winter. I used to use them in cars that did stream crossings and they had no issues with working first press afterwards even after having a bath in cold water.

I'd like to test them a bit longer to see if they retain okay and any refinements I need to make to suit different tolerances on the housings, creep over time, movement in the housing, etc - I do have a solution now that solidly bolts them in if need be, but I'm hoping to do without that to keep...

That was fast, I now have 3 volunteers local, so we'll see how it goes :D

Et viola, I have also got a local victim/volunteer willing to trial them and keep popping back for me to check. Although another wouldn't hurt, if someone is local.

I could just do the simple ones with flat outers, rather than making a clip in one, as that would make it cheaper - they tap in with a mallet so they're pretty tight fitting - I just don't really want to find someone with a big stainless exhaust vibrates one loose :D Although, I suppose you...

Yeah, I used the honeycomb on his and it was perfect right up until he sold it, so I know that'll work well. Although his was just flat outers and just got glued into the housing - I'm trying to make this one clip in to make it easier and give it enough to cope with the housing tolerances - I...

I don't have the mount in hand yet - good old Royal Mail, so the best I can do for the minute is:

Where are you based Rich? I've an OE mount coming in the morning to remake my CAD model from, I'll probably have a prototype out after the weekend.

Anyone local to me want to be a test dummy for an uprated polyurethane one that doesn't also give you tinnitus and remove your fillings?

Probably, pretty lucky it showed up on the first set as soon as I went to bleed them. They still sent 2 more sets out with the exact same problem even after me telling them what was wrong though. Cowboys.

Can't find it, it must have been before I switched CAD setups. Anyone local got an old one, or some accurate dimensions?

Renault don't spend money on things for fun ;) It'll be to deal with a specific resonant frequency - like the rubber mounts you get halfway down driveshafts.

Gear 8 is decent oil - leave it in. As for J&R, I have never met a bigger shower of shite in the replacement parts industry in all my years, they supplied me 3(!) sets of calipers with the wrong thread bleed screw fitted - so that as soon as you touched the bleed nipple it took the thread out -...

I made a custom one of those for my brother when he had the Clio, I'll see if I can find the CAD model but I can do you tailored stiffness/positioned ones if I find it.

Blue NDX's made a decent road pad on my 306, but when I did fade them they left deposits all over the discs. They weren't bad for fast road use though, wouldn't have like to test them hard on the track however.

Yeah, they bolt into that flimsy bit of tin at the sides that you can flex by hand and do sweet fa.

There's a lot of different compounds, and some firms aren't picky about what they supply when the EU-market ones are cheaper.

What he said^^ He's sound.

^^They do indeed, 4wd unit, Autotronics developments in rotherham have a 2wd unit too.

Hmm, did want to try to stick to Renault stuff with it being a Clio shell, but it looks like the current RX-8 engine mated to a Mazda 6 diesel gearbox would be perfect...

Cheap Safari car, so huge wheels bump the gearing back up a bit after the diffs, aiming for about 120mph top end. But get there as fast as possible :D

It's going in a spaceframed car with a 197 shell over the top. It's going to have to drop down through another pair of diffs (~2.5 or 3:1 roughly) to give it 4wd, hence the need for taller gearing in the 'box itself - I'm trying to avoid packaging a pair of transfer boxes otherwise.

Hopefully going on a worked-over Megane 250 engine or perhaps a saab 2.3t, but I do need massively tall gearing out of the 'box itself, hence looking at diesel gearbox on the petrol motor, something that gave the equivalent of 250mph@6.5krpm in top gear wouldn't be terrible...

Maybe, certainly doesn't look like I can use the standard box/flywheel/clutch setup from either a 197 or Megane 250 like I was hoping :D Not unless I can get a 2.4:1 diff made anyway...

I need about half that again - 150mph@3000rpm would do it in top gear. Don't think it's going to happen when you say it like that though...:D :o Have to see what I can get diff-wise, if I can get it to the ratio I want then 100@3krpm might just do with a longer ratio on the final drive.

Might help, the few I've found ratio's for are still nowhere near high enough though :(

nm, found some, looks like they're still nowhere near long enough, be setting off in 3rd gear. Re-think needed!

Does anyone know what they are, or even the megane 175 dci ones? Going to need some longer gears in the racer and I'm wondering if a diesel box will do the trick rather than fork out for custom parts.
