Modifying the 335d...Is this stupid?

I'm looking forward to getting the ACS springs fitted next week to our 335d tourer, which I am growing to love more each week. The articles below on the Volvo V60 Polestar, and to some extent those on the new Jag XF-RS Sportback have me contemplating how far could I go in modifying the 335d to be my own version of some kind of M340d! I just really like the idea of practical and relatively subtle (compared to other overt performance cars rather than an out and out Q car) everyday car, that goes like stink, and rides and handles very well.

http://www.autocar.co.uk/car-review/volvo/v60-polestar

http://www.autocar.co.uk/car-video/v...olestar-driven

I suppose that some would suggest it may be just easier to buy a car that is that already - something like the Alpina D3 tourer, or an Audi S4/RS4.
However I already have the 335d and won't be changing it any time soon, and with the high mileages that we do I'm happy with the perfomance/economy balance on offer.

So what I've got in mind is:

Suspension: Fitting the ACS springs next week, and see how they go, but future possibility is ACS RS full suspension change, which is uprated ARB and adjustable dampers etc

Power: ACS or Hartge ECU to put it up to 350bhp+

Brakes: M Performance discs and some uprated pads (only when brakes are due)

Looks: Some M Performance spoilers and skirts and some different alloys - perhaps BBS CH-R or the BMW 405M, on non-runflat Michelin Pilot super sports (only when tyres are due anyway)

Exhaust: An aftermarket option to give the 335d the look of the old 335d with split exhaust pipes

Interior: Nothing much needed, but maybe get the M Perf steering wheel, or the existing one re-trimmed in a nicer leather.

If done all in one go I reckon this would be about 8k of mods, though it's something I would do over a couple of years I expect. Can't rationally justify it particularly, but as I plan to keep the car for the full model lifecycle, and use it extensively, I sort of feel I can!

My view is if you are planning mods then do them as soon as possible to get the most use/benefit/enjoyment from them. We all keep our cars for a finite length of time so to me, there is no point in putting mods onto a car over a 2 year period only to sell it a year or two later. If you are going to keep it 5-6 years, then fine.
Otherwise buy a car with everything on it from day one, as you say.

Sounds like a plan, what will the ecu upgrade do to performance figures?.
Has it not got enough grunt with 313 ps?

The car can take more.

For example chris harris got an Audi S4 to go as fast as a RS4 just with software

I am now understanding why some buy the 335d, and even then getting them remapped as my 330d just doesn't feel quick anymore! It is of course fast enough for my needs, and overtaking is a breeze, but it certainly doesn't wow me like the first few weeks!

But then i think why spend the extra on a 335d or remap when you'll just get used to that as well!?

Why is everyone so negative on the leather used for the steering wheel? I believe it's Napa leather which is high quality leather. Especially compared to the concrete leather seats.

Nappa? I'm surprised if so, it just feels a bit cheap compared to what I've had in my BMW's previously.

I'd question why mod any car you only plan to keep for a couple years!
You are right in that if you plan to spend x amount modifying a car, then the earlier you do it then the longer you stand to enjoy those benefits for. However, as Teaston points out, once you get used to something then you want more, so if you phase the mods then perhaps you get 'more' in another way, in that you get to enjoy each mod as it comes, get to look forward to it, the pleasure of the moment after it's done and you get to see or feel what differnece it makes, and then enjoy the impact it has for a while before the next one!

If I do go down this route then it would still be done over no more than a couple of years though, and then I'd still have a good 4 or more complete years with all the mods done.

Yes that's a great video, which I only watched a couple of weeks ago! That, along with the Volvo Polestar reviews, is what really got my in to this idea. However, unlike Chris, I would want the exterior/interior/cosmetics to be as good as the mechanicals!

...On an airstrip drag race. An S4 is as fast as an RS4 in everyday driving.

Just as a 335D/i is as fast as an M3 in everyday driving already.

Well speaking as the first one on here to be daft enough to part with considerable cash to try and improve an already pretty good 335d.....

Springs wise, it's damn close now to D3. There are roads that show up it's short comings but it is SO much better than standard, you're willing to accept that, considering it's a relatively cheap fix, it's brilliant. I would love to try the RS setup.

Power wise, you'd think the standard 335d was sufficient but I did find it lacking when I got back into George's car. I now love the low down thrust. Is it enough? To keep your licence, you probably don't want much more. At least it's usable whatever the weather and certainly surprises other cars.

Came onto M25 today ahead of what I later found out was 330d xDrive (saw another later on A22). From 40 upwards, was interesting how much I pulled away (and 330d is hardly slow).

Bizarrely my MPG has gone up to over 41 on the last two tanks. Win win as far as I'm concerned.

Should you mod the car? I'm just hitting 19k now and by the time I move on to another car, it will have 110k or so on it so when looking at amount I have spent out per mile, it's dirt cheap. Looking forward to next 90k.

Wife and I had a conversation today about what I'd replace me car with if I could have anything. Funny thing is I can't actually think of a better non showy all rounder.

PS Tengocity, if you're on Herts on Monday, I'm at Pinewood Studios on Monday (not a million miles away) if you fancy trying :-)

Very good points there, doing the mods over a period of time for the reasons you have mentioned.

I agree. I find the wheel a thing a beauty and pretty much perfect. I'd rather have the wheel leather than the Dakota thank you

Really looking forward to getting the springs fitted on mine. don't think I've been this excited since I ordered the car, probably more excited even.
I'm not expecting miracles, but looking forward to an improvement from standard springs.
Power wise, I think any of us wouldn't mind a bit more power and torque, regardless of what engine we have..... But for me, I drive 90% of the time in Comfort or sport and if want that bit more I put it into sport+ - then that makes the car feel a bit more special. I find this DOES make the car come alive and it's almost like 2 cars in one, compared to any car I've owned in the past. Previous cars feel one dimensional in comparison, power wise.

Whole point is Andy that the power upgrade is far far more evident in Comfort than anything else.

Makes it an incredible package. You'll see once you've got springs done just how much you'll use comfort even when pressing on. Sport + now used far less but nevertheless is bonkers

Pretty sure its Nappa , nice fine leather too, makes Dakota look so rough, but thats understandable for durability.

Do any of you guys know if fitting the acs springs to a f31 xdrive is a diy job for a resonable home mechanic or specialist only .
If i can save 250 TO 300 for a days graft i would be well up for it.

Sod doing it yourself, I would imagine you need to check the geometry and possibly tracking, and don't you want to keep your warranty? 300 seems a very reasonable price
