Yes he did, plenty of cars leave me in the dust , corner exit speed is not optimal. I'm getting an LSD, Rear-sway and rear sub-frame bushings installed to try and help. I know driver is the biggest mod, but I'm already at a point, where lack of LSD is really hurting me.

So, let's see how I do

My axle seals come today, while my LSD comes tomorrow! I can't wait. A lack of LSD really hurt our cars. Hopefully this will help me in those corner exits.

I got my LSD done just before Christmas. The difference is ridiculous... you will wonder how you did without it.

Was it a big adjustment, driving the car again? I'm adding stiffer sub-frame bushings and 20mm rear sway-bar. So I imagine it'll be easier to spin, will probably need to adjust driving style a bit.

I did the same thing, I got the UUC Swaybars, powerflex diff and subframe bushings, and the OS Giken diff done at the same time.

To me, the car seems FAR more controllable, not less... it grips and goes rather than shimmying around and snap-oversteering randomly... you can drift it if you want or you can tuck it in if you want, depending on what you do. I think the car will be tremendously easier to drive with the LSD and swaybars, myself.

Good to hear, I do have a shorter wheel base, but let's see. At least it gives me confort in knowing what to expect a bit. I'll increase the limit little by little to get used to it.

Thanks for the feedback.

Swaybars are good but if you can I would just get a higher spring rate (if you can adjust that). Having a stiff swaybar puts you from soft straight to high stiffness of the chassis. With springs, you can stiff stiffen the ride to the EXACT stiffness, while the chassis still has a little give (which is what you want). Regardless, when you add stiffer springs and/or swaybars, the car will just be easier to rotate. So mid corner if you are understeering, give a little more gas and the rear will rotate just enough to compensate. I think a tighter ride is easier to control and is faster, it just takes more skill and concentration to get the car to do what you want it to do, haha. Hope that helps a little. Good information from Dallasboosted!

Thanks for the info, sway-bar's already in and so are the bushings. LSD get's here tomorrow and should be in then. There's no doubt that I'll have to adjust my driving, but looking forward to it.

I am looking into springs as well, but still researching what I should get. There's allot of information (sometimes too much) to glean through, and figure out what I need.

Again, thanks for all the info, always helpful Turb0mike

Yeah, no kidding. BMW did not make it easy for you guys!

[pkimM3r]

Uh oh!! Time to let them wheels spin lol. There are guys who are fast in stock cars. Thats my goal.

Now when can i steal my lady's 135i and tske it out?! Just dying to but for now the f30 will do till that new m2 comes out dammit. Such a long wait!

Good Job Yandy!!!! So about how many seconds do you think your LSD shaved off?

This time around, still getting used to it, about 2-3 seconds consistently.

I believe next time, there's another 2 in there. With proper drivers coach, which I plan on getting, there's probably an additional 2-3 (without speculating too much).

Yandy, what brand of LSD did you install? Also, what other parts besides axle seals did you get for the LSD install, and how many miles are on your car?

Thanks

I got the Wavetrac + the Install Kit (Stock 3.08 Gearing core exchange). The axle seals were the only thing "needed" for the LSD install, of course and fluid which the shop had in hand.

I ended up replacing Diff bushings for stiffer ones, since the diff was going to be replaced anyways, might as well upgrade that, but it's not necessary.

Can you describe the difference in feel on track with the LSD vs. open diff? This is the first car I've had that came with an open diff and now I have an LSD. It feels dramatically different on the street but I haven't made it to the track yet.

Ah, I see. I'm at 102K miles, and I have a bolted diff, so its a much simpler install. Was just wondering if I would need these other parts:

It's a very different way to drive the car at it's limits. You have allot more exit speed/potential but with some care and taking notice of simple hints the car is telling you. I did sub-frame bushings and swaybar (not sure if you did). But the car's allot more oversteer happy, nothing uncontrollable just have to pay attention to it.

If you go into a corner too hot, and feels like the car's drifting out (understeering on you), it's a great sense of control, tapping the throttle and having the car rotate. With an open diff, I could never manage to do this, it'll just spin the inside wheel as you know.

When you're at the apex, or just before, you'll feel the difference in throttle input right away and power to the ground. Car actually glides through those apexes now, it really is something to experience from the Open diff side.

With those miles and if you have the parts, might as well. However, all I did was order the Diff and Axle seals. According to Fred at ER that's all I needed and he seems have been right.
