What wheels are you going to use?

[EL_3grab]

Atm I have these

Re-drilled (5x112-14mm) Motegi TRAKLITE 1.0
17x8 - ET45
Forged
14,99lb per wheel




I'll be going custom 17x9 once I get the wider fenders

[TyrolSport]

17x8 ET45 wont fit with TT spindles and stock fenders.

I need me a longer inner tie rod! Here kitty kitty!

I am not clear as to why you need a longer inner tie rod? if the tie rod mounting point on the passat spindle is the same as the R - shouldn't the tie rod length be OK?

[Siliconrane]

CRAMBONE!!!





As I read this thread, I become more interested in a lot of the parts that are being thrown around. I am probably going to follow in the footsteps here and in the APR thread. It looks like we can shave a little bit more off the car's unsprung weight aside from the ususal wheel / tire combo. Aluminium Half Shafts and what-not are very sexy. Although not related to unsprung weight, I am super interested in the TT-RS parts - especially if we can get a fairly easy bolt-on solution that does not cost as much as a kidney.

Maybe "need" was the wrong word. So today we will talk about inner tie rods. If you will, please see the below pic of inner and outer tie rods: (Top TT, Middle Golf R, Bottom my secret for now):



The jam nut on the Golf R tie rod is placed where it would be when used in combination with the TT LCA and Passat spindle;



It has 20mm of thread engagement(remember with the added camber, we are pushing the spindle further away from the rack, hence less thread engagement). Some people may be comfortable with 20mm of engagement. It is probably ok for a street car, but I am not comfortable with that given my usage. People argue about the minimum thread engagement required on a tie rod. Some say that it should be at minimum 100% of the diameter of the thread. The stock thread is 15mm. the 20mm of engagement that I have would make those people feel comfortable. Flaming River, a rack manufacturer, likes to see 250% of the diameter, which would be 37.5mm in this instance. I am ok with 200%, so my goal is to get at least 30mm of thread engagement.

So the easy answer would be to use the TT inner and outer right? Nope. The TT inner tie rod does not have enough thread engagement to our rack. Notice how the threaded portion is shorter:



Yes, I could have machined the TT inner, but why do that when there is another inner tie rod available that fits perfectly? Unfortunately I cannot let on as to which inner tie rod I used just yet. Again, this is me being anal about thread engagement. I want to make sure my son has a dad around.

[timmyd]

I re-read a couple posts - I missed the fact that you didn't use the passat LCAs and went with the TT LCAS - the added camber adjustment in the ball joint mount would change the thread engagement of the inner and outer tie rod.

I have the passat LCA and Spindle setup sitting on my tool box right now waiting to be installed on my R32 - and thought it was odd that you need a longer inner tie rod.

If you ran Passat LCAs you won't need the mystery inner tie rod - but would lack the additional negative camber.

The TTRS LCAs and Spindles are the same as the regular TT. Where did you get info on aluminum half shafts? I'm looking at a TTRS right now and they appear to be steel

[TyrolSport]

Stock wheels fit over TTRS brakes with 10mm spacers. You have to place the wheel weights inboard else they may hit the calipers.

TTRS wheels on GolfR





The wheel can be bolted on, but rubs the strut:





3mm spacer is all that is needed, but wider fenders would be needed for tuck.


Will stick out past stock fender.

The calipers are nice but the rotor compound appears to be garbage as reports have been seen where they are trashed after one track day. I also know someone that warped a set on a weekend of spirited driving. Racingbrake.com has a nice 2 piece replacement that also sheds some weight.

I stand corrected - I thought you mentioned that you had located Aluminum Half-Shafts. I will have to read some more.

[mikeh6]

Did you confirm weather or not the mk6 gti aftermarket sway bars are the same?

a few degrees of camber, that tire will tuck without a problem. With enough camber, you can also tuck the tire and poke the wheels http://www.youtube.com/watch?v=zhT3C...layer_embedded

That picture is with -2.0 already!

[ToeBall]

If all you're after is weight reduction and camber, why not do the Passat parts and just throw a couple of these in there?



I could be wrong, but being able to pull the top of the tire in instead of pushing the bottom out would give better fender clearance, wouldn't it? I talked to the techs there today and they have about 19mm of adjustment in from stock, so depending on ride height, that can buy quite a bit of clearance at the top of the tire.

Being an engineer, I love all this techno babble!! Thanks

Brembo brake installation and rigid collar discussion coming on Monday.

[Ryan E.]

The whistles go woooo woooo

[Ryan E.]

just noticed your last comment on the rigid collars, mine came in but were for a MKIV R32, so a new set should be here tomorrow or Monday. Looking forward to what you have up your sleeve...

Mmmm. Rigi-Cola. So much better than Coke.

[SilverSquirrel]

Great Thread!
I have a question for you guys..

What is the STOCK unsprung weight, (F and R), for the MK V/VI chassis? I realize wheel/tire and brake differences, just need to get into the ballpark.

[sh{}e]

Final test of the intake. Installed the high-flow filter provided with the Carbonio intake in place of stock. More improvement, but there is still a slight bit of restriction:



I'm not worried about it....I'm guessing maybe 3-5hp tops. Once I get my hands on a VWR intake, I will repeat the test to see if the restriction goes to zero. Remember that restriction is only part of the equation. You can remove your filter box completely, have zero restriction, but have less power(engine sucking all of the hot air it wants from the engine bay). I am gathering the MAF and IAT logs now to see if we are reducing restriction AND reducing air inlet temps. That's the golden combination(while maintaining adequate filtration of course!).

Would you use the g/s reading from the MAF to compare the stock intake and aftermarket? I was thinking about doing this along with IAT to put an end to a lot of the intake debates.

Bump for this great thread

Tuesday...

Um some of us where at/on track on Sunday and might have needed to rest a bit yesterdeay, oh that's right you wouldn't know excuses excuses excuses they continue way to go Tex

Yeah driving was out for me on Sunday.... Not the way I planned on spending the week or weekend but stuff happens.

But excited to still hear updates from Mike, poor excuse for delays... "Playing on Sunday..."

[ftillier]

Hey Mike, is the extra curve of the TT tie-rod end for clearance from wider tires at full lock?

[TyrolSport]

I have to machine the Passat Alu spindles to get my new Brembo kit to fit(passat spindles have thicker brake caliper carrier mounting bosses)......Will hopefully have this done tomorrow.

Curved tie rods are for wheel/tire clearance from what I can tell.

[_leo_]

where you able to move the battery? i wonder how hard it would be to run a cable from the current location to the rear, and i wonder what size, my guess is 000 copper which will probably weight in around the area of 50 lbs so it might make it a wash to relocate it

[Boosted2003!]

Like I said, no harm per se "...ride better and handle better" is an oversimplified, subjective minefield. With the current state of the OEM damper calibrations on VWs, only a very skilled R&D driver would be able to tell the difference, should everything else be equal (as in, no decreased roll moments due to higher roll center).

As far as daily driving the Enkies is concerned, I live in a semi-rural part of Michigan. It's bad enough that I'm already on a first name basis with Martin at the Tirerack... due to needing replacements.

Yea, I don't have huge amount of experience as you. I know one can really tell damper calibration in a circle track stock car. I use to run a 2300lb tubed out mini stock with a Mustang II suspension that was close to factory mounting positions. The bound and rebound was very interesting to play with. Especially, when braking hard into a corner.

I am going out here on a limb that with having reduced corner weight you would be able to feel how well the damper kept the tire planted to the ground.

BTW: You would be very interesting person to talk to cause this is one subject that can't be learned through a book but by experience of people like you. My old neighbor taught me a lot about setting up a circle track chassis.

This is funny this is the last post of the thread. I was going to ask you Mike what you did for brakes. I take it that your not using factory Golf R brakes on the Passat spindles since the brake caliper carrier mounting flanges are thicker.

Not sure if the the part number is just different for no reason but I found the part numbers for the carrier for mk5 r32 and 3.6 4motion passat to be different. Not allowing mk5 brakes aftermarket brake upgrades to be used on passat spindles.

You don't think machining the mounting flanges down will affect the strength?
