So "god spec" is it REALLY not rubbing?

[ABPDE5]

So verdict is in- the tires are just wide lol. The RE-71RZ appear to be on the wider spectrum even for 200TW, and likely run wider than their predecessor RE-71RS (*but note no measurements were taken so take this assessment with the appropriate grain of salt). So it is just a clearance issue. The bump stops appear to be cut correctly for the Eibach springs (which they fuckin should be, despite my existing reservations the shop that did them did have an established known good reputation).

That said the rubbing is extremely minor, and only occurs on very substantial bumps. Not anything I'm likely to come across during an autocross, but possibly a DE in certain conditions. It's just barely coming into contact with the felt/plastic liner so no damage is being done, just some extremely minor scuffing on the sidewalls, visible in the picture I shared above. Rears definitely more than fronts due to the extra camber. No other contact is taking place... and truth be told it appears to have actually mostly resolved already via "self-correction" from the tire wearing through the mm or so of liner. I noticed 3 "incidents" of rubbing on the ~1 hour highway drive to the shop this morning (so like <.01% of overall driving) - and absolutely zero on the way back. (Also the shop may have done some pressing/shaving with the fender liner but if they did it was minimal effort). I do have yet to run through my favorite bump that caused all this- but even still now that I know it's not actively hurting anything I think I'll just slow down a hair more when going over it on these wheels.

So TL;DR, it's just a "is what it is" situation that I'll just have to live with. With some input from a couple pros to I can live with that. Just chalk this up to the first known case to experience rubbing with the "god spec" configuration on 275 200TW tires, on the DE5 platform (which may have slightly less clearance than the FL5).

Good to hear. You scared me!

My anxiety just be like that, my bad lol.

I would have done the same...

My wheels have a slight rub on the rear fender well—18x9.5 ET38 with PS4S 275/35 tires. It’s not severe, but as others have pointed out, even FL5s running the so-called “god spec” setup can still experience rubbing, and most end up needing a slight fender roll.

When it comes to wheel fitment, I’ve always taken a cautious approach. Just because a setup works on one car doesn’t necessarily guarantee it’ll work the same on another, especially when different brands come into play.

How much room is left for you guys on the inside? There should be quite a bit.

I suppose you could just run a wider wheel to get that offset still and then stretch the rubber of the 275 a bit more. I believe apex confirmed a 285 wider fit with some extra camber.

Glad to hear the shop found no issues.

Love the setup, and glad to know the rubbing isn't as big of a deal. Did you have the suspension setup before or after DSC Controller? If so, did you have to change it much?

Thanks, and yeah the DSC was the latest addition. I had DSC themselves do a little baseline tuning as they're right down the street from me, and they had just recently released the unit for the FL5/DE5- but the good news is that anyone with springs will be able to use the tuning they did as the new baseline map. Sounds like some folks have received the downstream result of that tune (this was in early December) and have shared positive feedback.

Also good to know my suspension wasn't compromised for when they did the tune .

I'm currently running a 18x10 +40 Apex VS5-RS with 275/35r18 Maxxis VR2 and previously a Toyo RR in the same size. My alignment is -3.2° front and -2.0° rear, 0 toe all around.

The Toyo RRs definitely seemed to run narrower, but haven't experienced any audible contact with either tire. I have noticed a little black rubber transfer on the inside of the fender/quarters every so often and just spray it off with detailer.

I have noticed the RE71RZ runs really wide. Saw a FL5 running 275/35r18 RE71RZs at the track and you could see how much wider they ran on a 18x10.

Have you had a chance to do an autocross event with the DSC controller yet?

I have. It fucking rocks.

Limited sample size I know, but here are the Top 25 results from that day out of ~80 cars; 10 was me. The two Miatas ahead of me (one was co-driven) were also on RE-71RZ and SCCA coach-level drivers and configurations- and FWIW those two GT3s just above me ROUTINELY take FTD at most of these local events. The Ecoboostang down there is a Nationals-level driver. I feel like I left time on the course.

TL;DR, it "wakes the car up" from a suspension perspective the same way a tune does from an engine perspective. The tires helped, clearly, but the DSC plays no small role. I could NOT get the car to push or run out of grip. I finally feel like I have a ceiling left in the car again; where things left with the last event I did, I felt like it was easy to "overdrive" the car. No longer.

10/10, would buy again.

You just convinced me to hit the "buy" button. Thanks
