another update (or lack of) to my considerations with bushings.... been diggin in the workshop, I remembered that years ago I had a 'linbin' full of assorted Nylon bushings (remnants of the clearout of 'TAS' or 'Trans Auto Sport' who were a motorsport supplier in the late 90's / early 2000's (like Rally Design BUT higher quality at the time) when they went bust in about 2004ish & I helped a friend who bought the redundant stock move & catalogue) so diggin happened....  these are the collection of the sizes I had (were a lot of smaller 'top-hat' bushes that might fit for the antiroll bar droplinks? (not shown BUT if theyre a close fit a cheaper option than a rosejointed link)  these are 45mm & 43mm outside diameter so re-machinable to the 40mm Mazda used for most of the wishbone bushings  Also, a bit of trawling found this drawing  found on MT.net in the usefull thread www.miataturbo.net/suspension-brakes-drivetrain-49/miata-bushing-megathread-heirarchy-diy-delrin-dimensions-info-discussion-87573/cannot believe I'd missed this previously, good info also listed there is a link to Energysuspensionparts installation pdf for front suspension bushings, convieniently having the inner-sleeve dimensions listed   and a quick search found the rears....  so, now I need to strip wishbones, check dimensions (was taught as an apprentace that all fabricated parts will be of a larger tolerence and may be distorted due to heat, not an issue with rubber or poly but a harder material like plastics, nylons, delrin / acetal or ptfe can cause installation issues  ) then get machining...... oh, how I love plastic swarf, a 'cats-cradle' that gets every-bloody-where  more thoughts & random waffles to follow.... Rich. |

TAS rings a bell for some reason! Showing your age I suppose not that I can say much, I used to buy Group4 Escort fabrication parts from them (more expensive than RallyDesign but were higher quality - for a while anyway) Rich. |

Speaking of resurrection, when do you intend resurrecting your ever growing pile of components into a car once more?

Would you like me to offer any advice on getting things progressed swiftly and efficiently? Your project management skills would be a boon in this case… and you could offer guidance on cylinder head fitment. |

If I am to be an external consultant, I would be happy to take all your money, gather all your knowledge, then tell it back to you in a slightly different format so you think you have received good value for money |

Reminds me of the definition of a consultant, “a person who borrows your watch to teach you to tell the time”…

I'm still struggling deciding which way to go on mine, I think one of the big issues being is the oem rubber on a more "road based" car the twist and flex in the rubber is actually part of the suspension, without it you lose the "travel" as it were over road imperfections and bumps. The second issue is movement, cheap poly bushings and even good ones are flawed when it comes to great, superpro do a good job but most will squeak and at worst bind meaning you control arms will take the load (and eventually break). I'd almost decided on superpro at one point but I'm still not convinced I'd be happy with them, and they are not maintenance free either.
There is a pillow bush kit from a company in Japan you can get on RHD but they are £1200 + taxes + shipping for a full kit (ouch).
I think I'll probably end up on Ilmotorsport rubber bushings the max5's use due to the cost of OEM, but I'll have to live with the worry of potentially having to re-do them if they don't last... hmmm.

I'm no fan of polywatsit bushings - seen too many failures and think they're a fad for the masses (but usually easier to fit compared to oem types). standard Mazda bushes are designed as part of the suspension - to the extent that the rear suspension geometry alters under breaking to 'toe-in' as to the 'pillow bush' setup, theres a company in the USA making / fitting kits to wishbones (but less Scene-points for atlex ) There is a pillow bush kit from a company in Japan you can get on RHD but they are £1200 + taxes + shipping for a full kit (ouch). More um.. info on this ? jdm obsessed Scene-monkey as to 'pillow-ball' suspension, you don't need to spens a fortune, Saab 95 rear hubs have a pair on each side and can be adapted (~£10 for 4 on ebay!)  even nearly look like rubber bushes  these are cheap, have a 12mm 'bore' so good for lower / inner wishbone - subframe but will need a larger tube welded into the arm to fit... more bodges to follow Rich. |

) then get machining......
