when i offered to sell the skid plate to you and you mentioned you were going to make your own, did i make a face like 'yeah, ok'? because i feel like i would have, lol. those motors run so low in the chassis.
only 100 miles? that thing is still low mileage!
Hahaha yeah, you totally did. Hindsight is 20/20... Should have bought Dan's skid plate haha.

Hey stew, what are the spring rates you have on those bc's? I'm thinking about following you on those..
They normally come 8k front/10k rear but I special ordered 10k/12k and have them set to 13 clicks up front and 15 clicks in back, it rides like a dream. However when I bought mine, there were no vendors in the US who carried bc coilovers for an e30, so I had to wait a total of like two and a half months while they made them from scratch and shipped them from Germany. Hopefully you'll have better luck than that hahah.

^thats exactly what rates I was thinking. Thanks man. I'm excited to get them. If you were to do it again, would you do the same thing?
Absolutely. I have rode in tons of lowered cars, but none of them were as comfy. My evo when I owned it was on the ground, and at times it felt like shit. I recommend BCs to everyone man.
When I was this low it rode almost as good as stock. This was also before I adjusted the front camber so the fitment was kinda meh. All of this coilover talk is making me miss driving it again lol.

10K front, 12k rear? Should be the otherway around. higher spring rates in the front, lower rear. Unless stuff is Different in Subaru WRX STi's. But I doubt that.
I've been doing a ton of research on this for e30's and for some reasons all of them have lower spring rates in the front. Do not know why.
sk8 or die

My springs are 315 lb/in front 570 lb/in rear. The rear springs are stiffer because of the leverage involved in the trailing arm rear suspension design. If you go to a coilover design that relocates the spring onto the damper, then you need to reduce the rear spring rate to achieve the same balance (without doing the calculations I would estimate that I would need to go down to a 380-410 lb/in rear spring for example)
A 240sx for example, typically has equal or stiffer front springs than the rear (if my memory serves me properly this morning) due to it having a multi-link rear suspension where there is little to no leverage in the suspension links that would require stiffer springs than normal.

Idunno subaru motors work sideways so who knows. The BC's come stiffer in the rear, and for the most part I thought most coilovers come stiffer in the rear? But I wanted the car to feel super tight so I got higher rates, and it definitely does.

If this thing isn't on the fucking GROUND when I see it. I'll be dissapointed in you Jake.
If these "m50 into e30 chasis" mounts let the motor sit ever so slightly higher, then yes, shit will be dropped. If they dont, shit will also be dropped.

Idk man, S13 coils are the same way, stiffer front slightly lesss stiff in the rear. I'd assume due to fat ass engines. But hey, potato.

Dropped or dropped. I like it. Me too. I bottom out everywhere (my oil pan and new bumper) So I'm right along with you babe!

Jake, what tire and rim setup are you using by the way? I'm thinking about doing a 15x8. I can have some decent grip and also a bit more tire to keep it cheaper. Also, are you okay with all this thread derailing? Haha
Thread derailing? Not giving a fuck man
Im hopefully helpin you out with your future setup so its all good.The sportmaxx in the pic I just uploaded were 15x8 on a 195/45 tire I believe? The car was scrapping everywhere. It was great. But I sold those and now have these:
These are 17x7 with 20mm spacer up front (205/45) and 17x9 with 5mm spacers in back (215/45). Goodyear Eagle GT's all around. These are for cruising/meets/not drift day.
I just run all spares for drift days.

The ways of the e30 explained. This is good info! Thanks

I might step it up to a 16, but I feel like keeping them smaller would be lots cheaper for tires, and when you drift, you definitely use tires.
Just an FYI, if you're going to drift, go to a junkyard like gibsons in neenah, buy their shitty used tires, for $10 a pop. or buy new starfires. Those will last you plenty of drift days. Starfires last for eva
