Looking good man. Spotted your car in OC a couple days ago. We should cruise some canyons sometime

Looks like you're investing in all the right places.

What harness bar(?)/GoPro mount are you using?

Whats the piece at the bottom of the cluster?

Love that steering wheel, reminds me of the prototipo.

A few of us are doing the speedventures autox on the 21st. You going?

The piece at the bottom of the cluster is an led shift light that I put specifically for autocross I would have a habit of riding 2nd gear to long bouncing off the revlimiter.=slow
Now the shift light blinks bright red screamin shift and that = faster lap times.
I made it so it's adjustable. You can set it to flash at any rpm that you set it too.

I'm loving the steering wheel really makes a big difference


The 21st is my 9 year anniversary with nicole. So you can count me out have fun out there. You should try disconnecting one end link on your rear sway bar. Passenger side is easiest since the exhaust is out of the way. Try it for one run and see if you like it.

Wife got me a set of harnesses for my birthday
Schroth Racing
6 point cam lock
3 inch
pull up lap belts
clip in 5th and 6th points




I wasnt satisfied with the choices of reinforcement plates avilable so I made my own.
Purchased 3/16 steel plate
made a template
got a layout to make the most out of the material i purchased to have little waste.



marked out the cut lines




i could only mockup the eyebolts on the floor.
I made just a 4x4 plate for the inner lap belts until i had time to drop the exhaust heat shield and exhaust and make the inner lap belt reinforcement plate

everything lines up so now its time to drill some holes

proper brideport vertical mill

holes drilled bottom square plates ended up looking exactly like the other ones for inner lap belt plates


quick coat of paint so they dont rust




the seat belt rail that the seat belt slides back and fourth on has a bolt that goes into the e30 chassis floor.
its a metric head bolt but uses an american thread.
its a 7/16-20 1.5 standard thread pitch.

I was able to get some through Evasive Motorsport in LA.
cheapest place i found

http://www.evasivemotorsports.com/mm5/merchant.mvc?Screen=PROD&Store_Code=EM&Product_Code=SR-SG22&Category_Code=SCHROTH-HARDWARE

doing it again i would have purchased 2 long ones and 6 short ones.

I bought 8 38mm eye bolts
2 where a good length for the stock seat rail
the other 4 stuck out to far towards the ground
the other 2 stuck out to far towards the driveshaft


used masking tape to make them all the same for a cut line
bench vice and a quality blade made it easy



cut down to a good size



ahh this so :hitler: drilling holes into car goes against my core but necessary


quick spay paint to keep it from rusting



lather up some silicone sealant to keep the water and rust out

done


and a good picture of the inner lap belt plate
I could not find anyone with this plate documented on how they did i hope it helps.
the Center support bearing is completely in the way of where i wanted to install the eyebolt so its just barely behind it.





CSB is right here


All done
just needs to be
driver side


passenger side


5th and 6th belt are annoiying to adjust. do it out of the car make them the same and ziptie the excess

Woot I bought these for myself as birthday present.
I have really wanted these for a long time but they are just a bit expensive.
I purchased a set of 60mm top hats and 2.5 inch top hats
I have a set of 60mm helper springs and 2.5 helper springs to play with.
I also ordered extra hardware just to have

I love taking everything apart.


mocking it up.
E30 Camber/Caster Plate,
60mm top hat
60mm Swift helper springs
2.5 to 60mm adapters that I machined myself



old setup
new 5k mile old stock upper bearing
custom top hat 14mm bilstein shock shaft
2.5 id hypercoil springs 330 lb 6 inch length




start with this


cool tool i purchased a while ago.
its a 3/4 socket with a hex shape on the top to grab it with a wrench and you can fit an allen tool inside to hold the shock shaft from spinning.







all gone no impact tools required

out with the old


camber plates in with the slot for caster adjusted to be close to stock currently running 9 degrees of positive caster.



strut bar back on



new springs
thanks to Mike an Engineer at Eibach for answering my questions. he is currently in the market for a badass e30 coupe




old vs new


Hypercoil 2.5 id .440 compressed length 4 inch free length


and pics with it in the car




Got the ride height set with 1/16 of an inch difference from driver front to passenger front with me in the car.
thats close enough ballpark before doing a corner balance.

[TeXJ]
