That's exactly what I am removing , black compost.

So with that setup you will be close to 600nm of Torque, a damp road will see you lose traction at 100kph with a big stab at the loud pedal. It looks like you have convinced yourself to go for the small rear setup based on info that is not applicable to e92/90 n54 cars. All the BMW advice I ever read about square setups is aimed at low to mid power cars not torque monsters. Good luck with that but I guarantee it will not deliver what it is you want. The stock E92 does under steer a wee bit but good tyres help immensely. What really helps reduce under steer is the M3 front control arm setup as it gives you more camber and much stiffer bushes. Its not hugely expensive and install is straight forward.What you can do without any guard rolling is fit the M3 spec setup 235 265 tyres. I have had my 335i for over 3 years now and I have experimented with a few setups including a 245 front and 245 rear setup off my old e46 and it made no noticeable difference apart from having less rear grip and more flashing dash lights. The inherent issues with E92/90 handling are huge amounts of torque from low down with no LSD and a front end geometry that is not quite aggressive enough. The E90/92 platform is actually a power over steer monster that is held in check by electronics. In 4 odd years of trolling through internet articles on getting the e92/90 to handle none have ever tried going smaller at the rear, it just defies logic. I have driven an E92 with a torsen LSD it had stock M sport suspension and very good tyres. All I can say is that is where my money is going next.

Ok I think I found the problem or at least one of the problems. The cowling scuttle was full of decomposed leaves and dirt. Its a complete bitch of a job to fix as there is just no room to work.

Seriously there is a proven way to make any E90/E92 handle like a an M3. Fit an LSD and program out the E Diff settings then fit M3 front (rears if you have the money) control arms. You can fit stiffer springs but if you already Have M-sport springs you will be pretty good as the rears especially are already quite stiff. Do this, fit decent tyres and all you will have to worry about on track days are overwhelming stock brake pads (easy fix) and an extra oil cooler to stop it going into limp mode when it gets too hot. However if all you want is pretty wheels and a reason to justify small wheels then ignore this.

Seriously I cant see how a 235 is anywhere near enough tyre for a 335i, sure stick with 17's but at least look for a 8.5 or 9 inch wide wheel so you can fit standard 255s or 265's back there. The money you will pay for a soft tyre that has grip will be more than a good 17 inch 255. BMW never ran a square setup on any of the high HP e90's and this was for good reason it will turn into a pig. If you leave the electronics on all that will happen is your dash will light up and you will go nowhere, if you turn the stability control off you will go sideways or become a one tyre fryer. if you give it a tune and lets be honest the 335i is just so easy to get extra HP and torque from, it gets even worse. Leave your current setup on and buy and LSD, then you will see why the e90M3 handles so well.

As a 335i owner I would ask why you want to give up rear tyre contact with a smaller tyre wen you already have a car that that is traction limited. I am exploring how i can go from 255 to 265 or even 275 width at the rear. However I am not sure how much you like going sideways or making tyre smoke.

So the floors on my E36 coupe are wet, quite wet. The car has a sunroof is that the likely culprit? What else do I need to check?

I have located an m54 rotating assembly in CCH but the seller wont ship. Anyone down that way able to pick it up and hold it for me until I work out how to get it to Wellington?

If you lower it to the point where the top of the tyres are at or fractionally below the guard (back wheels) you will have a small amount of visible camber. Nothing excessive and nothing to worry about. Eibach springs and matching shocks Koni, Bilstein and bushing upgrades will give you a good firm ride. I had a full Ohlins road and track setup on my E46 along with bigger anti roll bars and new bushes. This setup was superb in every respect but Ohlins are pricey.

If its US sites they might not always have the engines that were offered in Europe & Japan.

Yeah but at least an SLR 5000 has some credibility, that thing just looks dumb.

I like it, I remember looking at an E60 front on for the first time and thinking bloody hell only a mother could love that face. But as it happened I grew to love it too and realised it just took a while to appreciate the headlight design.

I need to control my 335i, it just cant get the power down without the traction control intervening. MHD (V6) has given me a lot more torque and it hits like a sledge hammer and even on a warm day with perfect traction I will get a stuttering takeoff as the tyres try to break free. I know I need an LSD but in the meantime what are peoples experience with the linear throttle and the Limit Power By Gear option. To be fair I tried the linear throttle but switched back before really giving at a fair go.

For all the 16 inch wheel boys Hyperdrive have Goodyear Eagle F1 Directional 5 in 225/50/16 on sale for under $200 a tyre. Please note I have no affiliation with HD just started looking for myself and thought the deal was worth sharing.

Ok guys I am seriuosly considering manually converting my new e36 323i to manual. I have a g220 from a 4cyl so will need a 6cyl flywheel and clutch. What are the options, dual mass singles mass, what size? The M52 b25 will likely stay stock and I have a 3.46 diff ratio so might have to change that.

Yes got that arse about face. M54b30

I have a Getrag 220 kit so I think a manual conversion and just keep it original. Of course if some one said I have an M30b54 rotating assembly.....?

Oh yeah.

If they are 135i springs then they have a lower rate than E92 springs 350 lbs/inch vs 456 lbs/inch. Some E92 springs might help.

I admit it I am a big E36 Coupe fanboy. I know the E30 is the golden child but for me E36 Coupes are my favourite shape. So for a very lowly amount of cash I picked up this Hellrot 323i with a broken starter motor. Like most E36's she need a bit of tidying but I am getting good at fixing them now.

Yes the arm is upside down. One end has a fixed bushing and needs to be installed at ride height as it influences the spring rate because the arm has rotational flex on the bushing. I did the M3 upgrade but went with Tein springs and extra thick pads. I have a vague memory that standard 335i rear springs are quite firm to compensate for the small rear roll bar.

So after languishing for 6 months my 335i burst into life with the first push of the starter button. My DME had blown 2 of Mosfets that control the injectors. At first I thought it was the coils as I had one die last year so I replaced them all but the problem persisted. The error code 30BB sugested the Mosfets so I ordered some ex the USA and finally found a guy who could replace them. Its not a job for amateurs but GP electronics in Lower Hutt did it and no issues. After reading all about it I decided to replace all six Mosfets just in case. Now all I have to do is use a full tanks worth of 6 month old 98 octane. I also replaced the battery as the BMW original was 12 years old and wouldn't hold a charge any more. Welcome back baby I've missed you.

Is it drive-able back to Wellington? Any thoughts on the misfire?

N54 cars are tuning heaven. Best advice I can give is . Get it serviced first new plugs as well. Then get a walnut clean of the inlets (Exteme Tuning in Ngauranga Gorge can do it). Upgrade the inter cooler easy enough to do at home. Replace the charge pipe. Then load a stage 1 or stage 1+ MHD tune. Then buy an LSD. A transmission service and tune is also worthwhile. When you get to the tune stage let me know and I can advice on tune options.

Great to meet you too, I really liked your 330i very tidy E46, just dont tell too many people how little you paid for it.
