Razorlab - 2020 LE build thread

Does SPL make anything good in your opinion? I am planning to upgrade all the suspension bits. I know for sure lower control arms I am going with Verkline

Their bearings have been shown to not be good quality. I'm slowing replacing most of my SPL bits with verkline and others if that tells you anything.

Hey razorlab, i've just installed my dorch ds25 as well and it's really shinny ?... i love it. Btw, have you noticed how much louder the ticking is? I can hear it a little bit in the cabin.

I've also been looking at the logs and they seem ok but i do notice on this FF MHD tune it tends to overshoot fuel rail pressure but it recovers...with the tu hpfp i never really noticed this...did you notice anything similiar?

Yea it's for sure louder. Sounds like rod knock, right? haha.

Can you post the full log?

Hey Razorlab, do you have recommended alignment specs or suspension parts for a car that does a combination of track and car bowling?

Current specs are

-2.3 camber all around
front toe 0.22
rear toe .12
Caster ~7.8

The car tramlines all over the places on the street and wanders around the lane at wot. Behaviour is less pronounced on the track.

Current setup:

tire setup is AD09 285/35/r19 rear and 265 front

15mm spacers rear and 13mm spacers front, stock wheels

H&R springs.

that front toe seems off to me

Are you sure your front toe is correct?

I would go for zero toe in front.

Is that rear toe total or per side?

"Are you sure your front toe is correct?" - Yep

"Is that rear toe total or per side?" - total

Yea go zero front toe and that will help with tire wear. I run zero in front.

For the rear, if you want more stability, run more toe-in total. I run about 1.5mm in each side.

If you are able to get more negative camber in front, I would run at least -3. That will help outside tire wear on track.

What winter projects are you planning for the car?

on the flip side, I got around to doing the s58 injectors. Pretty easy, and you can definitely get by without using the special tool which is nice. When you hit your max injector window, what values are you looking at other than the flag?

Once Fuel Inj. Angle Start goes over 400.

I’ve heard on BMW forums people using a walnut blaster to remove carbon deposits on the intake valves, pistons, and/or cylinder heads. Either of you do this or plan on doing it (before the 30k recommendation)?

I don't think it is much of an issue on the B58's.
