Strict budget, slow restoration. *Now with moar budget*

Mine's already adjusted to be as far down as possible. Some people cut and thread theirs further down; I don't have that capability. That said, the main reason was for the biasing. E32 master cylinder is a symmetric bore whereas the e30 has a stepped 22mm/17mm bore. Therefore the 735 master gives you considerably more front bias, something this car doesn't need. Better bias is better brakin', not to mention trail brakin'.

Lol, of course you've already taken it to the max. How could i not expect that. Sounds like the ix mc will transform the cars braking.

cosigned. :p

I LOL'ed.

Yup. If anything, these cars need more rear bias. More front bias feels like you're stopping harder, more rear bias actually does make it stop better.

Whoa there Andretti. :p There are two good reasons for me to keep ABS:

1. Even 80s ABS works better than a groggy wh33lhop. I can threshold brake fine as long as I am alert, but if I'm not in the zone, well that's a different story, and frankly this is no different for anyone out there, as cool as you think you are. Shitty 80s ABS still returns much better stopping distances than a brake lockup.

plus fuckin' plus. don't be a f34r.

[tinkerputzer]

Nice work! Function over form FTW!

I'd like the pedal to sit lower for better heel-toe

It's a personal preference thing but if your not happy with the pedal height after the ix mc you could fine tune the adjustment with the turnbuckle that connects the pedal to the booster. I adjusted mine recently to just above the gas pedal and can really get a good chunk of it without over braking. I had to add about a 1/4" worth of spacers between the pedal arm and the sensor so the brake lights work. There is a pre-existing hole already in the pedal just above where the sensor is that can be used to bolt a stack of spacers in. If your feeling wh33lhopish though you could just tape some washers to the pedal :)

I don't know why you guys are into keeping your abs. 90's Abs systems are for grandma's that don't know how to both stear and break. Now, something like a e46/x5/e39 vintage has true "save your butt" control....but for an e30? Meh!

2. I codrive a lot of fun cars and I want something to offer in return. I've heard the good ol' "I can threshold brake just fine" from a thousand people I let codrive my car, and every time, I leave the event with flat spotted expensive tires anyway.

I am curious how the ABS will work with the PFCs, ASTs and R888s as I haven't tried it yet and the tuning won't really be ideal. I may wind up just pulling the fuse for track days if it's bad.

I've honestly never even braked hard enough to have my abs engage and i've been on the brakes pretty good more than once.

Lol. I have. :p

teehee

About dat lyfe eh?

[Wh33lhop]

Okay I haven't updated in fucking forever. So here's a recap of what's been happening lately. Also, sorry for terrible image quality.



I did an autocross thing



(car had terrible brakes for this so I barely used them)

Also I borrowed a set of bcaps and plebeian tires so now it looks stockish




teehee


Doing rear wheel bearings and axles


Bearing out!


Fuck this thing


New bearing in


Bearings and new axles in


Cut the AST's bump stops since there wasn't enough compression travel


Got the E46 some wheels and tires since the E30 isn't ready to be tracked yet


At thunderhill being racecar-y


Me being wh33lhoppy (this is actual clean driving and no crazy slides, tires too expensive)


Back to E30
This thing needs brakes, and bad. These should help (PF11, I didn't get no street pads bitch)


ABS is also not working, scored some good condition sensors off a guy who did a 5 lug swap.. oh and there is other brake stuff


Here was my ABS relay... fuse link popped. Just soldered in a new one (read: small strand of wire) and that did the trick.


blahdy blah, changing the master cyl


old E32 735i master vs. new 325ix master. The E32 master has a bigger bore and more front bias. I'd like the pedal to sit lower for better heel-toe and better brake bias, plus I wanted a new part, so I grabbed an ix master.


Car up on stands getting fully bled


I fucking love pressure bleeders, does the hard work for you


This little guy is useful too


So far, a decent success. The ABS works now, probably for the first time in over 10 years. The brakes... well I think there is some air in the ABS unit because I've never been able to get them to feel as they should for years, even after many full system bleeds. So, next up is to bleed the system while cycling the ABS unit. Also, doing front wheel bearings as well as an alignment and 3-clutch diff. Then, the car may actually be fit(well, ish) for the track.

V710 is primarily an autocross tire from my understanding, so its temperature window should be condusive to such.

Honestly I would advise against an adjustable subframe with risers. I am planning on swapping mine back out for a stock one soon because 1) they fucking slip, and 2) they fucking suck to adjust with the risers. I have some posi-lock style adjusters which should help the slipping issue if I'm not happy with the alignment with a stock subframe. In theory, the risers give you back about a half degree of camber at any given ride height. However you will raise the rear of the car if you keep the same ride height adjustment, so that's something to think about if you're at the edge of adjustment or if you don't have adjustable ride height. Toe gain seems to be exponential in the rear, so risers should help considerably with that. I'll report back when I have the stock subframe on the car.

I have an all stock rear subframe (minus poly bushings). I would never consider fucking with the adjustable stuff or risers. Camber and tire-wear are both spot-on for my car, which has been a track-rat-only for the last 3 years. I would consider the risers on a street-only car but I've heard too many nightmares on the adjusters slipping.

[tinkerputzer]

Sucks your having so many problems with them! I'm glad to get an honest opinion from someone who doesn't baby their car. Going to just do the akg riser bushings then. Hopefully it works out for both of us.

That website with the camber and toe curves is quite a resource!

I've heard that about the v710's too. I'm going to stick with them to see how they do after the sub-frame is raised.

[Wh33lhop]

Some good info for the theoretical camber and toe curves in the rear (source)




AKG risers (and most others) are 12mm or a half inch. That equates to around a half degree of camber and thereabouts 40% of your toe reduced at the average E30 ride height.
