How do the Cobb springs ride?
Are they slightly stiffer than stock?

They are a bit stiffer than stock. They tend to bottom out on the oem struts. I think these are the gen 1 Cobb springs? They seem a lot lower than 1.5f and 1r drop. Would be paired perfectly with tokico d specs or koni inserts.

Gotcha.

I'll be looking at options in a few. Your drop seems nice

RPF1 17X9 +45 does not fit with stock struts and 4 pot front brakes. Rear wheel has maybe 3/8 clearance to strut. Front 4 pot hits wheel spoke. I had to put 3mm spacers all around and fits perfect with 245/40/17.+42 would be the ideal fitment for wagon imo.

I'm dropped on ISC coilovers, sorry about the delay in reply - currently in the middle east on a tour. My fenders are rolled. And you'll need a 3mm spacer in the back to clear the rear coilover. thats with the ISC brand at least

bumping for stoptech clearance.

I highly doubt it, from what I've read online that the +45 needs a 20mm spacer

for brembo's, not stoptech.

and here's the thing: my current wheels clear brembo's. they also have about 21-22mm of clearance with my stoptech's. so the maths says they *should* clear. just hoping someone somewhere has tested.

I'm talking stop techs also, the rpf1 in 9 wide +45 doesn't have a lot of clearance. I have these on my FR-S now, which has the same brake set up as the wrx I can measure the narrowest and widest points between the rotor and the wheel tomorrow if you like. Should be same clearances for the sti. I know the sti has a larger rotor so that in consideration with the smaller barrel on the inside of the rpf1 clearances would be very tight for larger diameter rotors

can you measure the wrx brake clearance for me? i can measure the wrx brake clearance on my current wheels and crunch the numbers.

the fact that my current wheels clear brem's and have 21ish clearance with the stoptech would suggest the stoptech's are 20mmish smaller than the brembo's. with the rpf1 needing a 20mm spacer.. i might be ok

sorry on the delay here, totally forgot to go out and measure yesterday but I just ran outside and took care of it

from the inside of the rotor:


and the outside:


I'm not sure where the stoptech rotor would be in comparison to the oem one but it should be very close. let me know your findings!

ah... yeah man it's the caliper that hits on the wheel, not the rotor. need measurement to closest point (to the spokes) on caliper

The rotor has nothing to do with wheel clearance.....

Apologies, my point is that you can measure the width of one side of the stop tech caliper with a pad placed in it to get a rough idea of how much the caliper sticks out from the rotor towards the wheel spokes.

I know the rotor has nothing to do with wheel clearance.... not a noob to these things

unfortunately the wrx brakes and the stoptech's are in different places though.

sorry to be a pain dude, i am thankful for the effort. there's just no way i can determine my clearance with just the rotor measurement(s).

Yeah no I understand this, which is why I said a rough idea. Even if I measure the wrx caliper clearances it's the same issue. The stoptech rotor size and positioning are different meaning my measurement of the caliper clearance would be just as pointless. Perhaps if I take the wheel off and measure the distance between wheel mating surface of the hat to the face of the rotor, if you follow me here? Compare that against the same measurement on the stoptech rotor then calculate the clearances by deducting or adding the differences if any?

well right now i have a set of wheels that clear my stoptech's, but my stock brakes on the car. i've test fitted current wheels with the stoptech's and gotten about 21mm clearance. if you were to measure the clearance with the rpf1 to the stock brakes, i can measure my current wheels to stock brakes and use the various measurements to work out whether they'll fit or not. i'll post up the calculations when i'm done for anyone that's interested.

1 & 3/4 inch at the widest gap



And 3/4's of an inch at the narrowest point


From the angles it looks like more clearance but the measurements I have are accurate

Hope this helps you out

alright SO... my pf01's have about 41mm clearance top and bottom of the caliper.

with stoptech's, it's about 21mm at closest point. so roughly speaking, the stoptech's are 20mm "bigger" than the wrx brakes.

wrx brakes have 26mm clearance at the top and about 20mm clearance at the bottom/nearest point to RPF1.

ergo... the stoptech's *might* touch. just.

but, the stoptech's are bigger (some 38mm bigger rotor) and so are closer to the rim/further out from the hub, and the rpf1's clearly have more clearance further out.

i'm tipping it to be very, very close if they do hit. like if i need a spacer, it'll only be a 3mm one. thanks dude!

excuse me lol, I meant to say it's 1 & 1/8th at the widest point not 1 & 3/4, half asleep at the time... But I see you corrected that, cheers.

Is there not anyone around you with these wheels? or even possible the +35's? then you could gauge it without buting the bullet and hoping. I'd really like to know as bbk's that work with these are limited and I really like how this offset works on the 86/FRS/BRZ platform.

Could you measure how wide the stop tech caliper is overall? And also the RPF1 Barrel is small compared to a lot of 17's, it runs with the stepped lip. Looks more like a 16" wheel inner barrel if I'm honest

i can but the overall width means nothing as the rotor offset won't be the same/have the same centre point. i can certainly post things up when i get near the rpf1's to test fit?

i have a wrx so, brz etc i don't think applies.

i'm not sure about the stepped lip part but the calipers are quite close to the bottom side of the rim on the PF01's. maybe 5mm clearance. they actually look absolute porn <3

The brz runs the wrx brakes up front. All wrx kits will bolt straight onto the brz etc. I'm just curious how wide the stop tech caliper is.

I'll measure the inner barrel for you if I can today.
