What did you do to/for your 1er today?

I assume that can potentially impact the steering feel?

I think if you are at zero or close to it - yes. Especially if you had more toe beforehand and got accustomed to the feel.

Interestingly the lightness/feel is about the same as it was before I put the M3 arms in. I had hoped they would improve it.

Hmm. Maybe you had little to no toe all along. If I recall correctly, when I put on M arms the steering weight didn't change much but I have no idea of what toe spec I had before the installation. The before specs at the shop are useless b/c toe gets so out of whack with the M arms. That's why driving to alignment is so difficult.

Find you specs and post them up here. Someone will have some ideas.

Took it easy today and only did both front fenders and a door. Very happy with the color and super excited to see it with all the carbon bits

- "M" gas, brake, foot rest pedals installed
- Anthracite black interior trim pieces installed

Next, Suspension!

Picked up a new battery, dropped it in & registered it with Carly. Pretty easy job really.

The pedals make a huge difference don't they? I didn't do the dead pedal as my car isn't an "M"....so I'm still looking for a suitable replacement.

Caster is also a big thing for on center weight and "feel" More caster is more "feel" and centering.

The further you tilt the line that the wheels pivot around aft the harder the wheels will push back. If it is vertical then no push back....if you could tilt back horizontal a huge amount of self centering.

Also affect how the car changes the cross weighting to the opposite rear wheel.

When I was racing karts it was a big factor in chassis tuning since you didn't have much else to "tune".

Oh.
Is caster adjustable by itself on our cars or is it a consequence of toe and camber (if one has the strut mount pins removed)?

Pics of the pedals?

[low135]

Absolutely in love with how the hood came out. Can't wait to get the bumper done and see it with all the carbon coming in

Looks wise, they look great!

One of the things the M parts do is move the bottom pivot forward and out, increasing caster and camber. The more you can move the top of the strut back (caster) increases caster.

I forget what else is adjustable but not much.

So if you have the strut mount alignment pins you get what you get?
Mine are in and caster is around 7.5 deg.

Correct.

[Ric in RVA]

What I did to my new to me 128i Sport 6 mt.

Redline MTL
Valvoline synthetic 75w90 diff fluid.
CDV delete. (If you have not done this....just go do it....)



Shifts better and the oil definitely needed swapping.

[iminhell1]

I added a little more boost.

Soon to follow, block venting. jeeze I hope not

Lots of carbon on order so that stuff should be coming in soon hopefully

Nice!! wheels and tire set-up?

Also kaputt

Just to chime in a bit:

-Caster is non-adjustable without caster/camber plates.
-M control arms give a little more caster, but the largest benefit is camber. (I didn't notice any change in steering "feel" from the swap)
-Subtle changes in toe go a long way to improve/destroy steering behavior in these cars.

Adding a little toe-out (a rule of thumb that I followed is just under 0.1 degree out per 1.0 degree of negative camber) did great things for my steering feel. I get reasonable wear on the street, but still ROAST the outside edges on the track (I need camber plates desperately). The steering was lighter (read better), more linear, and far more accurate on the highway.

I still have some tweaking to do (mostly to get the steering wheel perfectly straight) with my alignment...

[minitraveller]

Not exactly done today....but this past week I did the following:

1) Redline 75w90 GL-5
2) Redline D4-ATF
3) Mobil 1 0w40/Mann filter
4) Brake flush w ATE SL6 LV fluid
5) Clutch Stop
6) Blacked out front Kidney grills
