Hi, new 135 owner,looking at performance mods

[spunant]

Hi,
Just bought a 135i and have to say am very impressed by the performance and handling, use to race a two wheeled BMW and have now switched to four wheels.
Still have the need for speed and adrenaline, so looking to do some mods and take it to the track.
Hoping to meet up with a few of the locals here ( South Qld ) for advice on said mods and the ins and out of tracking the 135.
Is there a 135 owners club?
Here's a couple a pics .
Thanks for looking.

Nice one mate, if you have a bit of a look on the first few pages you'll more than likely find a bunch of "Mods for my 135i" type posts. Have a look in there.

Best of luck mate. Hope to see you around,next time when the meet isn't in a giant traffic jam (Portside) haha.

[spunant]

Thanks , have been spending some time educating myself through the search tool,
a lot to take in , so many choices, mine has a performance exhaust already, JB4 looks good then see were we go from there, should be fun.

[Harlequin]

Hey mate. Welcome and nice ride.

We don't have an "owner's club" per se but we do have meetups here and there, now and then...

[///Chase]

Welcome spunant!

Just get a JB4 into that thing ASAP!

Look forward to seeing your car in person

Guess I'd better repost

Welcome spunant, we are looking to have more regular meets, especially given how many newer members there are now it's worth looking into joining the BMW club super friendly bunch with regular meets/drive days/cruises/track days, I am in the process of starting up a 1 series register within the club so we can also host 1er specific cruises, tech days, track days etc

Agreed with yulook re: mod suggestions FBO +/- meth is really the best bang for your buck powerwise for these cars

[spunant]

Thanks for the replies, looks like I missed some interesting ones :-)
I'll check out the BMW club, look forward to meeting up with you all.
Weather permitting I'll be taking her out to The Test n Tune Weds night at Willowbank, just to get an base line of what she can do, any tips for getting a good launch ? ... its an auto.

Depends on what mods you have (well, you're stock i guess hah) and tyres.. start off with first gear 2-2.5k and see how it goes? Stock runflat's will be the biggest weakness, letting some air out could help a lot. Without DR's, FBO/Tune/E85 etc would likely be a second gear launch. Awesome to see someone getting down there, will be great to see what you run

[Giveway74]

If you are looking to track it, get rid of the run flats if you have not already
Also look into putting in the M3 rear subframe bushes and the M3 control arms.

While they wont make you faster in a straight line it will make it a lot nicer and predictable at the limit.

Probably a 2nd gear launch would be best if you are on the standard tyres.

Also, don't wait till redline to change gear, I think optimum is just after 6k rpm.

stock/mild tune power curve ends pretty close to redline doesn't it?

Last time i saw a thread with the shifting graphed - tuned/FBO with an aggressive falloff = redline 1st, a bit before redline 2nd (6750 or 6800 or something), and it falls to something like 6500 then 6200-6300 after that.

All depends on the specific torque curve.

At stock tune power levels I'd recommend still a second gear launch whilst brake boosting to around 3,000rpms or higher until you notice too much wheel spin. Less if you already notice wheelspin.

Welcome to the slippery slope of mods! And another QLDer! There's a few down on the GC so I'll let them chime in. As far as 135 owners club - you're here
My preferred mod path would be wheels/tyres, suspension, brakes and cooling, especially if you're going to be tracking it - are you more interested in straight-line or corners?

btw, SG is the best colour!!!

[Alext]

I think all you need for some more fun are better tires (Michelin PSS), some catted downpipes (AR), BMW PE and of course a tune (flash - Cobb then PROTUNE). A FMIC would help in summer.

As for the launch I would recommending learning on the stock tires before changing out to new rubber. Would advise learning to feather 1st gear to moderate wheelspin if you have manual. It's possible and once you get new, wider tires your times will improve even more.

[spunant]

Thanks again for the replies,
Got out to Willowbank Test n Tune last night but only got in one run due to work commitments and cars dropping oil on the track more than five times,,arrhhh.
Gotta say I'm pretty happy with the result. Took all the advice given here and got a great run in.
Wicked race number too 666

[spunant]

Oh and here's the time sheet.

Nice work, its now a slippery slope with more and more mods to get quicker times....

[flinchy]

13.1 @ 108 totally bone stock? nicee. 2.117 60' gives a few tenths available too

[spunant]

Not stock, l cheated. Found a used JB4 on gumtree and hooked it up
before heading out. Made a huge difference.
Best part was beating a noisey bad arse looking v8 commodore in the quite subtle looking beema.

[flinchy]

LOL really? nice find haha, is it the latest G5?.. find some strange stuff on gumtree.

I was going to say. You'd have to be tuned. Nice time though.

That's the exact time my manual 135 did with a tune only. 13.1@108mph

Full bolt Ons & some e85 pumped my mph up to 116mph the last time I went out.

Couldn't get a good time though, traction and clutch slipping were my biggest problems. best came out at 12.7
