My Z4 35i, unexpected purchase, minor project
I always like to make project threads for my cars so here we are with one for the Z4!
I came here looking for a 3.0 Coupe having always loved the shape, found a nice one and then stumbled across the car we eventually bought for a little bit more...
The budget had originally been 12k but a little stretch got us something a generation newer, more special on the inside and with some extras to make living with the car more enjoyable.
So unexpectedly we have ended up with a 35i in Havana, with a lovely spec including the extended leather ivory trim and dark wood that really sold me on the car.
It's a manual which to be honest was led by price, I didn't really have a preference between manual and DCT, so with the doppelkupplungsgetriebers costing a bit more with similar spec, the manual was an easy choice.
Our car does however benefit from a fairly comprehensive tune from Birds, using the Dinan software. The receipt documents considerable dyno time perfecting the map so it's nice to know it's 'just right'.
In terms of power the dyno graph shows peaks of 366bhp and 421lbft, which are impressive numbers! As you'd expect with a 3l turbo the curves are also suitably vuloptuous!
I would say the car feels effortlessly quick with nice surge through the middle of the revs, rather than being quite as ballistic as the numbers would suggest. It's so difficult to tell but I would imagine it's a similar speed to the 435d it replaces, perhaps a little less potent than the derv destroyer at all but licence losing speeds, due to the 8 closely stacked cogs and lightning fast shifts that benefitted the posh barge.
A couple of sweet heel and toe downshifts with the six singing though and I appreciate the manual box!
In terms of immediate plans, it will soon need fresh rubber so I'm deliberating over that. Are the Rainsports sufficient for what is ultimately a nice cruiser for us, or do I give it the best and go with Continentals...
Beyond that I'm looking at getting the CDV (clutch delay valve) removed, as the clutch action and gear change feels inorganic to me. I think I'll also give the 'golf tee' exhaust mod a go, being easily reversible it's worth seeing whether the difference is positive. Would be nice to hear a bit more of that lovely engine though!
A set of Eibach springs and spacers are also on the cards, as are wheel refurbs. Bit of research to do on the former and there's a decision to make on colour for the latter.
Anyhow, lots of rambling, if you've stuck with it this far then well done indeed!
A few pics ahead of the thorough clean it deserves when time permits!

Very good looking motor, great choice and relatively rare I guess.
All the best and enjoy!

I'd go Michelin Pilot Supersports for tyres and then get a LSD

For the rubber if you want to give it the best then you need to be looking at the Michelin Pilot Sport 4S. For a tuned 35i I wouldn't consider Rainsports.

Is there a strong agreement from 35i owners that the Supersports are superior to the Contis?
As a self-confessed Evo fanboy, I've tended to use whatever they've recommended:
http://www.evo.co.uk/features/18309/the ... t/page/0/6
As for the Rainsports, I drove a c.300bhp turbocharged mk1 MX5 in the damp on a set and thought they were tremendous for the money. I'm leaning as has been suggested towards a premium, no compromise tyre though.
As for the LSD, if one pops up for sensible money second hand, I'll buy it. I can't justify the cost of the Birds conversion on this roadcar with two track cars that both have slippy diffs!

Ahhh, thanks, I thought the 4 S was an update on the PS4!
Has anyone actually tried the new 4 S then?
Very frustrating that Continental didn't supply a Contisport for this year's tyre test.
Best go and look at the German publications' tests and see if they completed the two.

A bit misleading, perhaps?
A range of Pilot Sports is available.

PS4S is just a direct update on the PSS. The naming is misleading as it's not a successor to the PS4.
All reviews are feedback I've seen rate the PS4S as the best UHP tyre on the market. My own personal experience coming from PSS is that they grip better, are quieter and offer a MPG increase.

Great to have some real world feedback, I must be getting old as road noise and comfort are becoming more important in road cars!R.E92 wrote: ↑Thu Jul 27, 2017 9:56 am PS4S is just a direct update on the PSS. The naming is misleading as it's not a successor to the PS4.

Any supplier recommendations? Would quite like to try them but I don't think I'm prepared to pay a huge premium over the likes of the Conisports and Eagle F1s I've found to be excellent on other cars.

Interesting wear rate information in this test:

Has me considering the PremiumContact or SportMaxx as great allrounders...

I have been checking out prices for F1s recently and the best prices were coming from Black Circles at £114 each for the rears in 18"
I was surprised that it would be an extra £40 each for 19" and an extra £80 each for PS4S in 19"
So the difference between Goodyear and Michelin on 19" is £40 each rear tyre.
Quite pleased that I have 18" wheels now.
