what exactly does this hydraulic wheel do?
Does exactly what you would feel on any surface but from perfectly dry to complete ice. It raises the chassis from the suspension thus lowering traction on the corner that it's attached to. Lift the rears up to full height and boy, it doesn't matter how good you are...you're going for a ride and your front tires which aren't lifted are going to become the base of the pendulum. LOL. Lifting it up maybe 10% might simulate rain. Going to 50% may simulate snow/ice. Anything higher and it's just for fun...it's like half the car is in space. It's just a training tool that advanced driver training schools have to teach you the art of controlling an out of control vehicle.
Dang I love to participate in this!!! I think the main portion I want to learn is how to correct a spin in the event the steering wheel goes over 1.5turns. The main concern I believe is that I have no experience a full lock to lock correction in this car and I would like to practice the spin corrections. Perhaps the next skidpad day, I will have to try it out.
I'm getting tired of switching to longer bolts for the 12mm spacers every track day. I ordered some lugnuts for the car but still deciding on which wheelstuds to purchase.
Bimmerworld 82mm Bulletnose
TurnerMotosport 75mm Studs.
Hmmm
Well if you are in an uncontrollable spin and have the ability to lock the brakes, doing that prior to knowing what line your car will pick will at least give you a predictable line of "carnage" whether it's straight ahead on the track or angled off straight into the field of grass. :D Once you've slowed down then you will have to have quick steering work and unlocking the brakes to direct the spin somewhere else! Good luck with that. LOL
continuing from the other thread:
I had a moment of genius...

you're welcome ;)
Its definitely a solution! I'll be sure to try this out. The other option was to just ultimately remove it during track preparation :)
Thanks JP
^ Weight savings FTW!
I have the BimmerWorld 75mm "standard" or "street" wheelstuds. They make wheel changes so much easier. Can support up to 12mm spacers but I found with 5mm spacer on front, you have to take a little care when hand starting each lug nut before spinning them on with the impact wrench. If I had a 12mm spacer it would be even more work to start each lug nut. If you don't mind studs sticking out a little more or think you might ever want at 15mm or 20mm spacer, I suggest go with the 82mm ones. Note that BimmerWorld 82mm studs don't have a hex end so you need to lock two nuts together to tighten each stud (with red thread locker).
A bolt to stud conversion should be done on any car that sees track time imo. It makes swapping wheels/tires that much easier.
2013 going to have some plans! At least tentative plans..I hope I follow through with the last one..
Major Goals:
Jan 2013 Wheel stud Conversion
March-April 2013 - LSD
Summer - Fall 2013 - S54 Swap
and some other maybes
4300k AE
ZKW Lense Retrofit
EuroCharge Tune (really depends on S54 swap)
SS Pistons for the 135i Calipers
Upgrade Brake pads to XP12 and XP10 (stronger)
Best get to work
Cheering for you. That's a healthy list.
Thanks!
LSD and Wheel stud conversion is a 100% done deal for sure. The S54 swap really depends if I can find a donor vehicle.
You can always find a donor vehicle. That's never the question. The more appropriate question is if you've got the $$. :biggrin
Are you going with a E46 M3 diff (and subframe)?
I want a LSD badly. S54 swap would be awesome.... I'm jelly.
I know where to get a full M3 rear end from a '03(?) vert minus the R half shaft, so just one part you need to order. Down here in San Diego if you're interested.
Nice plans. If you go s54 swap would you just change out the whole powertrain back to the LSD?
From what I understand, the driveshaft for a 6spd follows the rear end you decent to use. (I could be wrong)
The plan is to get either a ZHP 3.64 LSD or 3.62 M3 subframe/LSD by March/April. ZHP 3.64 would use the ZHP drive shaft and the M3 would use the M3 driver shaft. I'm not 100% sure which one I want to do just yet. If i choose the M3 LSD it will be cheaper for parts but require replacement M3 sway bars and require alot more labor. It would make more sense to use the M3 LSD since I am planning to do an S54 swap.
ZHP 3.64 Ratio
Pros:
-Aftermarket LSD which allows great customization for the LSD characteristics
-Easier to Install than M3 subframe.
Cons:
-S54 swap can complicate the rear end situation (I believe it works but not 100% sure)
-Expensive
M3 rear end
Pros:
-Will make the S54 swap complete when finished.
-Factory LSD
-parts are less expensive than a custom zhp diff.
Cons:
-needs more parts to install
-requires M3 sway bars
-could be more expensive after labor
-condition of pieces sometimes can be unknown depending on seller.
I have a quick discussion question for those to have been following my build. (Thank you for your time)
Should I replace the subframe with
OEM factory bushing replacements?
AKG poly bushings?
AKG solid mounts?
I am uncertain how NVH effects correlates to each type of material for a subframe.
I just bought a M3 rear end for those who were wondering. :shifty

Don't know, but congrats on the M3 rear.
Sweet. Congrats
Go with the 90a poly bushings. And never increase the stiffness of one component with out increasing the stiffness of the one next in line.
I.E. don't put solid bushings in the diff and then keep the subframe bushings stock.
Go have fun with this one Derek!
From a GS3, this was sent.
Pics or it didn't happen!

It's not here yet..but here is the pic :P
Parts I plan to swap:
-Subframe
-Differential
-Sway Bar
-Half-shafts
-Driveshaft
The plan is to replace the bushings on the subframe/Diff bushings with either OEM or Poly Mounts.
I'm not 100% sure that the 330i trailing arms and brakes are interchangeable. I've seen threads on E46F that say it is not necessary but one member here (Jlastor) did write a reivew where the halfshafts did not fit the 330i trailing arms and that has me concerned.

I had a talk with Kalim tonight on the topic, and exhaust clearance with the subframe also came into concern. I might be choosing a new exhaust sooner than I thought. Also turner motorsports reinforcement plates pop into the topic. I am undecided on the reinforcement since I already filled the frame with the BMW Epoxy Foam.
Only a few concerns but only one way to find out! Hopefully I will be able to take pictures and have a good log of the install as well.
I strongly urge you to use poly bushings. You'll have to zip tie your speed sensors in place to keep functionality. Len has done this.
I was looking at that rear end on ebay.
Keep us updated.

These two pictures keeps me hopeful that the exhaust will work! Len got the 330i trailing arms to work and I am hopeful that is the same case for me. My reasoning to do so is to minimize M3 parts during the swap.
Wert, Cam,
I will definitely consider poly and the reinforcement kit. If it is significantly most expensive that OEM rubber, I may just opt for OEM Rubber since the BMW is still running rubber all around. Like Justin said, If you take care of the weakest link, the next link in line will be the one that gains the stress.
Vas,
they sell more than one. :)
After looking at the reinforcement kit by TMS, I'm not 100% I am able to do it. The instructions state that it is needed to cut the trunk top floorplan area to weld a new support bracket. I injected the structural foam into that area through the two holes next to the square area they cut out. Unless I cut it out and remove the structural foam in that area (however difficult that may be..)

My tentative list of parts to order, just waiting on the subframe to arrive so I double check if there are any other missing parts.. Those are Tischer BMW online prices. I have to check what my discount is from the dealership to see if its cheaper..
Performance technic charges around 1k for a subframe reinforcement, they weld in the plates and everything. I think 1k is for parts and labor, which is a pretty good deal.
