Rx8 project (probably same as everyone else but different and much betterer)

Yep and has to be done before tracking anyhow...  if there is going to be a time that poor fluid becomes a problem it will be then!

Buy a good quality dot 5.1 (not dot 5), and flush through the whole system through with it.  AP do a really good one that I use to good effect.

You don't need top end for the clutch (it does not get as hot) so a standard new dot 4 will do that just fine (just make sure it is a new sealed bottle).

Sound. I might get the brakes done at same time as I do the springs.

Once I have the springs on I'm going to get it 4 wheel aligned as it will obviously change things once lowered 30mm all around

Top tips.
Before bleeding empty resevoirs with syringe and fill means less bleeding.
Whilst doing springs lube all alignment bolts/threads and makes job easier for alignment man and lower labour bill. I actually feed them off myself on the fd prior to alignment.

What sort of stuff is there available for replacement in the suspension components? Adjustable control arms?? Or is it better too do the bushings? They nice and cheap compared too an fd!!

I'd always change bushes first for poly type. Made a huge difference to the FD, but realise 8 may not be too old, so your bushing may not be in bad shape.

They're 80,000 miles old. There's a lot less bushings to do too I think

Well how about this for a bit of good luck.

Last night the Forman didn't turn up on site because his car got blocked in at the hotel which was an hour away so he asked me to not tell anyway but look after the job and he would give me £200 cash for doing it. And then I played on the bandit in the services on our way back from Scotland and won another £100!!

So what should I spend that money on??

ARBs or bushings?

I'm thinking the arbs will have a greater noticeable effect but they're more expensive.

Bushings probably a harder and longer job but that upgrade should compliment the lowered springs going on greatly and it's a shit job done, I can get things cleaned an painted in the process too to further improve the car


Hmmm thoughts anyone? Any other suggestions?

Bushings...  The more you upgrade the more they will need doing...

Do them first and then they are done...  Don't forget rear sub frame mounting bushes as well, they can be swapped out to solid for better location.

As a predominately road car at the mo id concentrate on the springs and arbs....bushing will make it noisy and crashy over our bumpy potholed roads....
I wouls say whilst up in air having springs done fit some braided lines at same time....will give you lovelly brake fill and when you do go on track confidence consistence brake pedal( match with decent pads).

It will get noisy for sure... if you don't want that then don't do the bushes...  But if you are looking to explore improving the handling with other upgrades then not doing the bushings is a bad plan, as you start stiffening everything up the standard bushings are going to negate everything you are doing.

I would not bother with ARB 'upgrades' until you know you are un-happy with the standard ARB, if you don't know you want a change based on the handling then don't change the handling!  Get other things done first and then see how you like the handling before making adjustments for the sake of 'upgrades'.

The brake lines, now there is something we agree on   You could well spend you money on those and leave all the rest for later!

Is this said bushing a complete pain in the Arse to swap? I can imagine it being like the diff mounting bushing on an fd.

I can remember watching my dad make the bushings on a lathe that we put on my fd, that was loads of fun. Stopped all kinds of knocks and bangs from the scrap standard ones, which were knackered

Normally a pain in the arse - a press is a pre-requisite unless you are a sadist with a vice and a lot of time on your hands.
