Poly bushing question....

[shimmy]

Nothing wrong with the Milltek if you can get it for a good price,some on here just find them a little boomy,I think Bealo had one on his and liked it.

they used to be popular when Thorney was popular.

latest version was ok, previous was very droney, decent quality.

[Steve B]

In that case I will get the Milltek... I might ask about a group buy on them if I get some interest. Now does anyone decat or just stick with sports cats..??

[outnumbered]

I had the later version of the Milltek on my previous E46 M3, and I did find it quite droney & took it off after a few weeks. It also didn't quite fit properly, hanging marginally lower on one side than the other. Maybe I just had a dodgy one, but that was my experience...

My impression from this forum is that people have generally had more success with Supersprint.

Cheers, everydays a school day on here lol

As previously said most people run the OEM RTAB bushes with the Turner Limiting Kit, I have this too on my car.

With regards to the ARB bushes I am not sure they add much value, I fitted some to my car about 3 months ago and I am thinking of going back to my OEM bushes.

Personally I'm not a fan of Milltek, I found both variants I tried very boomy, doesn't help that I run a Supersprint non resonated centre section which just increases the boom.

Imho Supersprint rear boxes are the best for the M3.

Btw Steve, do you know my mate Bryan? he has a White RS which is always at SCC (Orange wheels)...

[Steve B]

Yes I know Bryan, nice bloke

Yeah he is, he's one of my best mates, his Focus is not half quick too, he dealt me a bit of a spanking in the drag race we had the other week :clown:

He did mention the other day when I went for brekkie with him that he knew some chap called Steve had sold his RS and gone to a CSL recently, I thought ah it must be you!

For the front end fit these...get the track version they are the best and not harsh at all for the road...

As for fitting exhaust and 100cell cats be careful running at WOT and High RPM for long periods...Reason for this is that due to the exhaust flowing better ecu needs to increase fuelling, however the fuel trims in the map do not seem to have enough compensation available and you can find the AFR getting a bit on the lean side....yes gives you more power but engine temps and combustion temps also increase.....etc etc....

if you decat you will lose low rpm torque...car will feel flat...

leading to possible HG failure ???

leading to possible HG failure ???

Well yes....it will accelerate the failure but due to the design of the block and the HG it will always fail even on a completely standard car.....

If you keep the car long enough you will undoubtedly have to change it again after doing it the first time!
