[ulises 335i]

so far we have exhaust, intake and ecu upgrades (reflash,procede,xede and turbo tuner). is there any thing else out yet? (throttle bodies, larger intercoolers) , etc. etc.

[edgarj]

1) PROcede
2) Non-rtf tires.
3) LSD, yet to materialize in final form, but fundamental
4) Exhaust, standard cat-back with x-over will do
5) Suspension, if you want pure track bebefit

[ulises 335i]

would putting some regular tires (non rft) make a huge difrence?

[edgarj]

Huge... especially with wider wheels that would support a F235/R265 configuration.... but the biggest difference comes from ditching the RTF tires. They are supprisingly grippy, but much less so than a set of PS2's or F1's.

[Walked U]

Yes

I have 18" 162s with Michelin PS2 RFTs. They are excellent for trackday use(Nuerburgring:check, Assen:check, Papenburg:check)

Dunno what the fuzz is about. Good RFTs are good RFTs, sidewalls are like concrete= more precision.

What about an Air Filter i read somewhere in the forum that it gives about a 4whp gain

I avoid the use of high performance Air Filters. Yes, you get less restrictive air flow but you allow more dust to pass through. Some ( especially M3 E46 ) users destroyed their MAF sensors due to the oil on the filters.

I agree but the filter i mentioned was made from a material which called tri-foam or something.Is there an aftermarket filter that doesen't contain any oil?

[Walked U]

Are you talking about the filter that borla made?

[fotiki]

Yes that was the one..

how much would it cost me to ditch my runflats and buy thoese ps2's....i also have the 162's in 18 inch? I tried the michilen web site but there's no price.

[1q2w3e4r]

the LSD is available, bavariacars in Australia sell the Drexler LSD diff (and are distrubutors) that was used in the bathurst 12 hour race that the 335 won.

I also wouldn't call a turbo timer a mod, they are a wank really. You don't need one, especially on a factory car or even a mildly modded one.

Tirerack.com. They usually have the best prices.

I found better prices at onlinetires.com, about $40 per tire better than tirerack.

Those PS2 RFT's you refer to ARE runflats. RFT = runflat

He asked about 335i. 335i has Potenzas, which are a lot better tires than the outdated PS2.

X-over is not doing any good for you.
Turbo-back is a lot better than cat-back. Who would leave the cats in the downpipes? So far only Supersprint offers Turbo-back, but you can get one custom made. Makes a huge difference.

ITG has a replacement drop in filter and AFE is coming out with one as well.
