'02 TJ with i4 -- Mid Life Crisis

semi mets handle heat better than ceramic
causes the pad to glaze over and you in fact loose brake performance.
if you look at OE friction material it’s all semi met once you enter the SUV truck category...

yes there is less brake dust with ceramics..  there is also less performance from a SUV/truck point of view.

[rejeep]

think about it this way...

you have a metal vs. ceramic grill, or pot

metal heats up and cools down
ceramic heats up and stays warms for hours...

brakes create heat, you want to dissipate that heat as soon as possible.. why have a friction material that holds in heat and can warp rotors/cause issues?

[jaysenodell]

That seems like a design flaw... what is the point of ceramics if they don't manage heat dissipation well?

[rejeep]

Has to do with vehicle weight and rotating mass..

Smaller wheels and less weight make for a better platform.
Plus your lexus doesn't want dirty wheels..

Ceramics work.. they are not PURE ceramic, but they work best when paired with high dollar rotors that can take the heat.

new lower control arm brackets welded on with some M4 skids

new arms in

front bumper bolts fixed

needs lower shock barpin bushings replaced- they have 1/2" of play

sMike, no sign of DW with 100mi today. Still going to look at the BPE stuff though.


Question: any reason I can't put in posts for the seat mounts instead of using bolts?


Explanation: I broke 3 bolts on the passenger seat. Was able to remove all but one. I've drilled it, but will most likely need to replace the nut thing in the floor. BUt that will likely just result in everything seizing up again. I figured, drill out the nut thing, run weld the bolt head UNDER the floor, then use a locking nut inside. Cut excess bolt above the nut and it will still be low profile. I'm actually think about about this for all the through floor stuff since I'm getting ready to start pulling everything off to address surface rust.


Thoughts?

i read that twice and have no idea what your asking or talking about lol  sorry

[jaysenodell]

Instead of nut under floor (welded outside tub) put bolt head under floor leaving stud to mount seat too.

Drill, re-tap, use grease or never seize on the bolts on reinstalling. I've been through this. It won't seize up again, took 10+ years of never getting removed to seize up the first time.

A bit o' progress.

Grill straightened to the point of putty covering the rest if the dents.

Working on straightening the new-to-me hood rear cross support.


I figure another 3 hours before I get to the temp sensitive stuff.

Never posted pics of the new LCA and smike's add to the lower mounts.

[Wingman]

Nice.  Why put the heim down?

[M4wdFab]

why not?  whats it matter?

[Wingman]

It doesn't really.  It'll see a little more rock rash down there, that's all.

Spent some time learning how to make smoke and sparks...

More pics before it goes on.
