eh the dust doesnt bother me lol

All I am saying is that until the brakes are up to temperature they are unpredictable as I have experienced them to not bite, ice mode or grab and stop on a dime. Just providing food for thought.

I run XP10/XP8. It always surprises me when I think they're too cold to work and you end up slamming the passenger into the dash. Also the squeal. I don't know how some of you deal with it but man is it high pitched lol.

Anyone measure bump & droop when installing coilovers? Roll Center?

Here are some pics of my bump(full compression, no springs) and droop (full decompression).

Rear full droop:

Rear full bump:

Rear Ride height:

Front full droop:

Front full bump:

Front Ride height:

Measurements: (from the top of the center cap to the center-most part of the fender)
Rear:

Fully Compressed (no spring): 317.5 mm

Full droop: 444.5 mm

Ride height (car on ground with spring): 352.425mm

Front:

Fully Compressed (no spring): 311.15 mm

Full Droop: 444.5 mm

Ride Height: 342.9mm

I may raise the front a bit, looks like I'll need a swift spring to properly preload the fronts, If I go any higher, the springs become loose. Only way to tell is to do a corner balance which will hopefully happen after I get my half-cage done.

When you did this. Did you watch to see how much the camber changes during full movement?

Would be very cool to know, at least as a reference. Would also love to know the changes in toe.

One can only dream. Watching Forza replay with live camber values overlay is fun, but not sure how realistic it is lol.

Unfortunately no, I haven’t aligned the car yet after installing my
SPL FUCA’s. So alignment is all outta whack. I do need to buy some mobile alignment tools to measure this kinda stuff.

Just moving the tire up and down, and eyeballing it.

Make sure you change your coolant heater hose junctions kids. Mine popped while I was gridding for the first session of the day.

oh nice! is the z1 piece the same thing you bought with just a bleeder port?

i have 8000 miles on the odo(only 2 track days), you think i should change it before my next track day?

bpchaos · 01-11-2021, 03:46 PM

You might not now, but it is a part that's known to degrade as you get heat cycles through it. My car has 163,000 miles on it, with maybe 15 track days, and it finally went.
