ok so ive finally ordered a full set of H&R Springs and Bilstein B4s all round so what else should i do while all the bits are off and easily accessible??

i have already done the rear B4s and installed new top mounts.
do i need to order front top mounts? should they come with them? do i need any rubber bump stops or dust sleeves etc?

i have already installed some lower wishbone lollipop power-flex poly bushes but thats it, im sure there is various bits i can replace if somebody could provide me a list of bits and ill see what i can do :D

thanks in advance :thumbsup:

* EDIT *

parts needed:

FRONT:
Top mounts
Drop links
ARB Bushes
Track rod ends

REAR:
RTAB (rear trailing arm bush)
Drop links
ARB Bushes
Upper control arm bushes
lower control arm bushes
 
Front Top mounts too Jungle :)

Have you upgraded the Front and Rear ARB bushes?

I'm guessing you have Polybushed the Lollipop bush (reading above), you could also change the RTAB (rear trailing arm bush) this made a huge difference on my car.

Another thing worth changing is the front and rear drop links, they are not expensive and are a doddle to change too. :)

yep already have lollipop poly bushes

so thats the 1st thing on my list, front top mount (any particular brand, i have Meyley HD on rears i think)
not touched the RTAB so thats also now on the list (these very expensive or hard to change?)
front/rear drop links also added to the list :thumbsup:

will try and find parts on ebay etc and report back here with prices and any DIY tutorials links so everything is in 1 place in case anybody else wants to follow and do similar :thumbsup:
 
Found this on another thread:

Front
wish bones
ARB bushes I also brought an m3 ARB
Drop links
Lollipop bushes
track rod ends

Rear
RTAB if you stay standard look in to a limiting kit
ARB bushes
drop links
Upper control arm bushes
lower control arm bushes

edited 1st post to include these, please suggest or advise on anything thats needed or incorrect so far :)

any suggestions as to what else i might need?
 
This is something I really must think about. Even with new pilot sport non RFT it still feels not quite right.
 
have you looked at replacing your front lower wishbone bushes (lollipop) as mine made a big difference when i fitted polybushes
 
I wish it could all be got from one place, it concerns me some complete kits of bushes have come with incorrect parts Iirc, car looks good jingle credit to you
 
thanks Mark, hopefully all the parts ive ordered are correct as ive had to kinda mix and match from diff websites etc i hope i got the correct part numbers!

any suggestions as to what else i need?

at least im on the final stretch for my modding (for now) after suspension, then wheels im pretty much done :D

I haven't changed anything at all since my indy said all was okay. I'd replace absolutely everything to get it handling well
 
Take a look at the condition of bolts which secure the bottom of the strut in place. It's a pinch bracket and I think the bolts are 19mm. They could be a job to get off and I'm pretty sure the OEM strut replacement process includes replacing these.
 
do you mean item 4 on here Mr PT?

It's an 18mm - a 19mm will try and round the bugger off (trust me!! :headbang: )
 
ill get a price from stealer later and get a couple of new 1`s. i remember the rears being in crap condition and luckily i had ordered 2 new 1s so makes sense to replace the fronts aswell while im there for a few quid, thanks for suggestion :D

Yep. They're not cheap - about £4-5 each.
