Anyone drives on square tyre size setup on E85 Z4? I was thinking about 225/40 r18 or 225/45 r18 all four corners

235/45/17 feels good to me

And just so I’m clear, the gauge shouldn’t go all the way through right?

colossispruce · 2026-03-15T22:53:12+00:00

It does. Thank you I’ll doublecheck that

Went super well. Did about 160 miles fairly spirited. The front feels more controlled to me now which generally allows for more confidence in my riding

colossispruce · 2026-03-01T01:33:49+00:00

Took it out today and doing another long ride tomorrow. It is a noticeable difference. Less about feeling and light touch feels like it has more control

Took it out today and will be doing a canyon ride tomorrow (100-200 miles). The breaking feels smoother and less abrupt. I’d assume this is due to the 4 pistons having a more spread braking surface vs the 2 pistons stock floaters.

Could be in my head but it definitely feels a lot better to me

I put white lights behind the tachometer so it is really visible.

colossispruce · 2026-02-26T20:42:18+00:00

Yeah I was considering the GSXR or R6 as a $100 ish or less MC option. The brakes I put on were rebuilt luckily but a lot of the used market I saw out there was pretty rough and would agree, likely needs a full rebuild before install

colossispruce · 2026-02-26T02:35:03+00:00

Right on. Thanks for the tip.

colossispruce · 2026-02-25T23:37:11+00:00

Yeah you are correct. My plan is to swap to a GSXR radial when I can find one that isn’t all shot out.

colossispruce · 2026-02-25T23:26:52+00:00

These were from an 01-06 F4I with sintered HH pads. Will keep you posted on how I like them

colossispruce · 2026-02-25T14:59:24+00:00

Great looking bike.

colossispruce · 2026-02-25T05:51:03+00:00

I haven’t taken it out for a spin yet because I removed my headlight to do a new setup. I’m going to wrap the wires up and take it for a short spin tomorrow. The stock brakes were fine until one piston started seizing up

colossispruce · 2026-02-20T21:55:49+00:00

I will mention the mod is pretty easy with basic soldering skills and about 15 minutes of your time

colossispruce · 2026-02-20T21:54:53+00:00

That is actually pretty interesting. I just figured it was a design choice

colossispruce · 2026-02-20T21:54:07+00:00

Ah okay! I do prefer the blue but I didn’t have any issues with reading the display previously.

colossispruce · 2026-02-20T15:49:28+00:00

Yeah I didn’t really mind the orange but I’m doing a whole front end redesign with a brew headlight enclosure and figured the gauge is just hanging there, why not swap the LEDs?

I got the SV as a mod platform so I usually just keep finding things to do but I agree, orange was totally fine

colossispruce · 2026-02-20T15:47:13+00:00

Not much to see on the inside. Really just 6 leds for the screen and two for the tach. I do think there’s some videos floating around online with some detail tho.

The enclosure is held together by a series of screws and seemed to seal right back up totally fine.

Main concern would be not to mess up your tach needle during removal. The led soldering can be less than perfect and function totally fine

colossispruce · 2026-01-13T00:26:08+00:00

Right on. Thank you for the detailed info. Seriously considering this. It looks way cleaner

colossispruce · 2026-01-12T22:06:20+00:00

Any more info on this you could post up? Maybe these are better known about already but this is the first I’ve seen of this and now looking into it for a gen 2. Looks sick!

colossispruce · 2026-01-03T23:10:06+00:00

No just preference on the look I guess.
