Eibach Pro Kit and/or Sportline Experiences

[BC504]

I already had my 18” wheels before installing my springs. Even with beefy 275/35’s, I didn’t like the horrendous wheel gap it had with OEM springs, so I decided to take the more aggressive approach and get Eibach’s Sportlines over their Pro Kit. No regrets, especially since I’m not rubbing at all.

No doubt the sport lines look better, but my back is very happy with the pro kit lol.

Despite the stiffer spring rates over the Pro kit, ride quality is still comfortable imo. I actually have the ITS ADS module on hand too, but haven’t installed it yet, since downsizing to 18’s and 35 sidewall already does a good job in increasing the comfort. Swapping the module should make it even more comfortable, but it’s possible that it could be “too soft” haha.

I've debated the ITS module, but once I put the 18s on they feel like they added a "bounce" to the ride that wasn't there before so I switch back and forth between comfort and sport suspension settings. Maybe it's a trait specific to the yokohama v601

how is the ride? Also what intake is that?

What is everyone seeing for rear camber specs with an Eibach drop, without adjustable camber arms?

Someone already mentioned it, but I'll weigh in that the camber drops to ~2.0-2.5 degrees with the springs. I have an ITS, and a Pro-Kit.

The other significant thing I'll mention about the camber is that the rear will be affected but not the front (significantly at least). To my experience, this leads to a noticeable addition of truly annoying understeer, but it almost certainly won't be noticeable until you're pushing the car to near its limits. I autocross 7+ times a year and noticed it instantly.

If this matters to you, I'd strongly encourage considering adding a set of adjustable lower ball joints to bring the front camber in line with the rear. I plan on doing this before I head to another autocross event. I may also add the roll center correction kit while I'm at it as I also plan on heading to an actual track again this year and I get the sense that any bump steer effects would show itself under those circumstances.

TL;DR, in hindsight after owning these springs for several months now, in my mind the proper route if you plan on doing any motorsports stuff with the car is to skip the springs and go straight to coils. I may end up doing that instead of sinking the costs more with the springs anyway.

First ride this year in the CTR. Have one side picture with the Pro-Kit. I’m assuming it’s fully settled, but it has only been driven 20kms. I will give it some more time.

That looks low. How is the ride?

This is the thing I'm worried about. Honda did some magical things to reduce torque steer and it seems like changing anything from the stock geometry messes with that. When I went to 18" wheels I immediately regretted it. I know some people say they can't feel the difference but I definitely noticed a reduction in handling.

I think you were a strong proponent for sticking with 19" wheels and your feedback has me concerned. I do think the Pro Kit is on the lower side though so maybe there is a happy medium on how much to lower the car (I just purchased Spoon springs).

The saga continues!

I was, you remember correctly. I stuck with 19s but changed the offset. I don't think diameter would change much about how the car drives but the offset does- a little, some people swear they don't notice anything. I just didn't like the way 18s look on the DE5 ... but ironically I may very well end up with some 18s eventually because of the tire choices alone. I don't think 19s are an ideal choice for a track setup- some people have actually de-beaded the Michelins on the OEM wheels on track- and tires definitely change the way a car drives so perhaps what you didn't like about the 18s you bought could have more to do with tires/offset? More sidewall could lead to a subtle change sure but probably in a good way performance-wise... different strokes for different folks. I'm not here to tell you what you don't like!

And to be clear, I don't actually regret getting the springs done, I just have some regrets. If that makes sense. Particularly regarding the extra considerations I didn't take to bring the front camber in line with where it should be for my use case. I got used to the added torque steer and it's not catastrophic... but there is probably I'd say 10-15% more noticeable torque steer by my extremely un-scientific estimation. Subtle enough to where it makes sense that many folks will say they don't even notice it.

I absolutely love the way the car looks now and actually notice how much the wheels are sunken in with the stock offset now that I have the OEM wheels back on for winter. But there is a trade off. And I wouldn't judge anyone for just leaving it stock lol.

Overall it's a good problem to have. The car is just really, really good from the factory.

Just ordered my Pro-Kit! Excited to finally get rid of the factory monster truck ride height

Your Type R looks fantastic. Love the drop and wheels. I’m going to order the Pro-Kit springs. Like how the drop looks!

nice, what is your offset? Have a pro kit as well that I havent installed. THanks

Currently running Eibach’s Sportline kit with no problems. TE37 SL’s running the “Golden” spec 18x9.5 +45 for a clean, flush fitment with Falken Azenis 275/35 tires. Also running aftermarket rear Camber and Toe arms to dial in the suspension and get the alignment back into factory specs.

Looks amazing! Do you have any
side shots?

Much appreciated! And here’s one, hot off the press.

Thanks

Pro-kit, 15mm spacers.

Nice! I’m about to switch back to my OEM wheels with 15mm and 20mm spacers.
