Do you have a link for the M3 microfilters? The upper part of the cowl won't be replaced so they wouldn't work if they mount in it.

[TurboBimmer]

For the M3 filters you need to replace the whole cowl. I got the whole stuff for around $250, the filters themselves being the most expensive part. But you can find generic filters for half the price.

Just replace the Heim joints when they wear out with whatever quality joint you want. The Rogue aluminum machining is fine, and even HPA sells the replacement parts.

Sick build. How do you like the Stoptech rotors?

Yep, that's the most reasonable approach right now. Ordered one of each thread. At least I'll have them on hand to get the thread pitch, etc. so I can order some Aurora parts too. Agreed the machining is fine, only the ball ends seemed kinda cheesy.

They look ok. Can't imagine they'd be anything but as good as Centric/Stoptech is. I have the Zimmerman rotors for the front as backup but doubt I'll need to switch over. I've glazed OE pads before 'cuz I was overbraking and thought maybe these would be a little bit of insurance.

Trailing arm sealed spherical bearings installed



Upper trailing arm bearing



And lower trailing arm bearing. Good shot of the welded in BimmerWorld inner spring arm bearing. Um, no it's not, it's the spring arm bearing at the wheel carrier. Duh...



And trailing arms installed



Suspension test to see if it will go as low as it's supposed to - check.



-3.8deg camber. Yeah, that'll work. heh

Measurements and calculations in progress to determine optimum ride height, etc. since I'm willing, or too stupid to know better, to have it set to an optimum ride height for the track rather than for the minefields of the streets.

[serotoninsteve]

That's some serious work, respect!

Do you have a part number for the trailing arm bearings?
I mean the one stamped on the parts or the box, not the Bimmerworld reference.

Perhaps they are OEM ones from a different make/car and could be ordered for cheaper elsewhere.

Thanks

Thanks, much appreciated. Lotta work getting this planned.

The trailing arm bearings are the only ones I didn't order and don't know. I do know they come from the 135i though and should be the same as those BimmerWorld sells, they say 135i too I think. So far the prices from TMS and BW are pretty much what the dealership charges for the same thing but that's just my limited experience. Hope this helps a bit.

Dropped off the Burger Tuning filters this afternoon. The DASH3 cable's already routed down into the dash, looks perfect to me. The fire suppression system bottle is mounted and they're plumbing the lines and routing the pull cable. Still gotta route and connect the CAN cable, install the Schroth harnesses, and the BMW LED lamps. I think that's pretty much it, looks like the chassis is reassembled but detailed torque and check with final routing of brake lines and cables, etc. probably still needs to be done.

Setting up the rolling chassis and road tests coming up I guess and then we'll run some dyno pulls while tuning it up. Taking a cue from Axiom's post about dyno'ing with adaptations cleared, we'll be sure to do the same thing this time around. Then I guess I get to start learning how to stall, er I mean, shift it with the new clutch. Gonna be educational.

Thanks for your response.

The 135i uses the same bushings as yours, so if they are from a 135i it would be good to know from wich different suspension part they are.
I've crosschecked pretty everything and can't find one that matches.

45,2 x 12,2 x 48mm should be the dimensions.

Could you ask them wich part they ordered for you please?

Thanks

No worries, I'll get the exact part number and let you know as soon as I can.

Well, it would appear I completely misunderstood the tech. Wouldn't be the first time.

They _aren't_ from the 135i which now makes sense but instead from the E46 M3. They're machined down 10mm to fit. So it would seem the only choice would be the BimmerWorld parts unless of course you have a way to machine E46 M3 trailing arm bearings. Huh. Learn something new every day... Sorry to have misled anyone, my mistake there.

Thanks for the info Pete, that's great to know and makes sense now.

I've found OEM part number 33326775551,
outer and inner diameter match but the lenght of the sleeve was 57mm.

So they've machined them down to 48mm then.

They are available for under 30€ a piece here in Europe, plus machining, still a bargain.

As little info they should also fit the toe arms as they have the same dimensions as the trailing arms bushings.

Thanks

That's excellent!

I forgot the track strut bushings are the same as the trailing arms so yeah these should work there, too. Nice catch! A lot less money than a set of aftermarket toe arms.

Great to know all this could help out, you're most welcome.

[ashmostro]

Wow, very nice suspension and brakes build and kudos for recognizing how much more important they are than the powerplant on the track!

Those are the first HVT's i've seen so far since the ownership transition from AST - how do you like them and what made you select that brand?

Finally, I'm running all three Megan arms on my car and am totally satisfied with the build quality and don't mind the weight. I'd rather have tough steel parts that I know are overbuilt in those locations. But to each his own!

Thanks, I've had a lot of help figuring all this out a lot of which came from these bimmerpost forums. I knew handling was critical but had no idea just how much until I started running DEs.

Watching an M3 driver muck up corner entry 'cuz I was on his tail making him nervous (as told later) and then being able to use all that torque to manage the exit with more speed at track out than I could manage was educational. Having my instructor point this out play-by-play was invaluable.

Obviously that's novice class and the gentleman's first time on the track but it really made an impact on how vastly more important handling and driving skill are than pure horsepower. And it reinforced my long standing opinion that excess horsepower allows important driving lessons to be obscured when one can so easily recover.

This build came directly from that experience, sort of the straw that broke the camel's back, er, bank account...

They look solid, no complaints on build quality. HVT is in use on the racecars at the shop and since they're local it's convenient as well I suppose. They're rebuildable and they custom build so you don't have to settle for something off the shelf, seemed like good points to me. Having them built for my car at a competitive price along with the shop's relationship with them and knowledge of their use, tuning, etc. made it a simple decision.

That's a positive report for Megan, thanks I appreciate it. Will have to see how the existing parts work out or if they can be made to work out, at least it's an alternative now. Can't find a way to buy the Hardrace equivalent anyway.

[ashmostro]

Glad to see someone giving HVT a chance. I myself just took off my AST 4100s in favor of JRZ's and I'm quite pleased. The ASTs were great, but the JRZ's are for sure a step or two above.

As for Hardrace - their arms are precisely the same as the Megan's. I'm pretty sure the only difference is th enow-pink color and the stick megan slaps on them. I'd say they bear no quality comparison to Megan's in-house products (which leave a lot to be desired).

Got exterior shots of the car? would love to see! Oh, and another kudos for swapping out the pistons of those brakes - that'd be their only weak point so I think you have a winning and affordable combination on your hands there.

Shiny side up and godspeed!

JRZ looks like a heckuva choice, not sure my little 328 is worth it at this point, we'll see. Long way to go before I reach the limits of the HVT parts, I think.

Not sure which quality leaves a lot to be desired, does Megan rebadge Hardrace?

Had followed the discussion over on 1addicts about the pistons and the cooling issues which is how F30 protection plates came to be added as well. RacingBrakes pistons are stainless but that's a different coefficient of thermal expansion than the aluminum caliper so Stoptech's upgrade kit from Turner Motorsports sounded like the right way to go instead. No regrets there. Will be changing out OEM pads for Carbotech XP10, front only, with HardBrakes 0.5mm titanium shims when headed for the track. Along with the track wheels and tires of course.

Pics from earlier this year running street wheels and tires. Will look exactly the same when finished except for ride height and camber, that and the steering wheel and shifter are different.

Sorry, that was ambiguous. Megan rebadges Hardrace. Hardrace clearly knows what they are doing but they are a small shop.

It's Megan that doesn't have the best reputation, but my point was that their reputation is irrelevant here as they are not the manufacturer of these parts.

I strongly recommend against the Ti shims approach as it can actually exacerbate overheating of the pads which can happen pretty easily, and is a band-aid for overheating of the fluid. instead of spending money on those shims, get yourself some Castrol SRF racing brake fluid and revel in the apparent inability to ever get it to boil! Plus this fluid requires much less frequent swap-out unless you are hardcore racing. Great stuff.

Love that exterior color!

And we have the same taste in interior leather color.... I heart me some saddle.
