I'm still on the stock 168mm small case LSD diff and 26yr old worn out axles. Idk how long these will last in a burnout lol. I'll be installing my 188mm diff & upgraded axles soon I hope.

. The car definitely needs an alignment and new tires (I'm currently rolling on 7 year old rock solid china shit). No traction in the first four gears.

Drove the car around some more. Haven't adjusted anything yet but I needed to put some more miles on her before I can do its first oil change. The car is loud as fuck. I'm gonna need to dynomat the floors and trans tunnel cuz it does get pretty hot after a lot of driving in 110F summer heat. Filled the car up with fuel and the fuel tank vent system I rigged up seems to work fine.

Great news! Post up some vids. I'm in for more feedback on the braking setup.

Bit of an update on this >>

Swapped out the Z3 P/S rack for a Z4 manual rack. Had to replace the rack side u-joint with a different spline count version. Also had to shorten the supplied Sikky shaft about 1.5" and redo the accessory belt routing. So far so good. The Z4 rack feels nice and solid, no belt issues and best of all no god damn oil leaks!

After fixing that issue and bleeding the clutch again I took the car out for the first time this afternoon. Drove around the block, warmed it up, checked for any leaks or issues. The car definitely needs an alignment and new tires (I'm currently rolling on 7 year old rock solid china shit). No traction in the first four gears. With the manual brakes, it definitely needs a BBK or at least non-base model vented rotors/calipers & higher friction pads.

Otherwise everything feels solid no leaks, no noise, no weird shit. Just need to adjust everything I installed (brake MCs, clutch MC, steering, suspension, throttle linkage, etc, etc) to my liking and clean up the car.

The single 16" pusher radiator fan fared well with 110F ambient temps. Coolant didn't go above 190F and it drops to about 185F while idling in the heat. However I already have a dual 12" puller fan setup which I'm gonna install and wire up later on. I'll go into detail when the time comes.

I'll try to get a video at some point. Hopefully once everything is set up right.

Yup that's pretty much what the exhaust shop did.

Apologies, i do not know why it posted a link and not a open file...

Nope never spoke with them after I placed my order. Wouldn't have helped much as I'm across the pond and shipping them back would be a hassle to say the least.

My headers are the basic kind. I think they modified it after they used my car as a prototype. They went from the regular flange to v band. I think that's where the length came from.

The final design did change to incorporate a v-band flange, but the collector sticks out for no reason IMO. The primaries merge right where they meet so I don't really see the reason for that additional 6-7" inches of pipe.

Mine are also vband. I called and pitched a fit... They tried to help but sent 4 sets that did not work. I was refunded for the headers after i had to modify them. I'm not complaining because they handled the situation however, when spending good money on "quality" parts, this shouldn't be a issue.
