Okay ladies and gentlemen, help a brother out!
Would you say 1/8"? 1/4"? More? How much?

The plan is to make this happen Sunday morning.

I’m on Sportlines and the front is .5 lower than the rear. I just got my shim kit in today and probably gonna install all 3 shims to give it a more level drop.

Thanks for the info, Jon!

I am starting to hear mixed things about these on some of the FB pages. Some guys like them and others say "meh". The truth is I'm really not that far off of a set of Tein street basis coilovers at this price point. I may end up pulling my H&R springs off and selling them to pick up some of the Teins.

Got my TruHart struts and shocks installed yesterday, and have to say I’m very happy with the new setup! I also switched from Swift Spec-R to HFP springs.

I didn’t install any shims in the front, allowing the TruHart struts to give the car a very slight rake. Basically the wheel gap seems pretty even all around.

First impressions: The HFPs seem to handle nearly as well as the Swifts. I’ve noticed that they do allow a little more initial body roll, but take a set quickly. The HFPs also ride a little smoother; I no longer feel every nuance of the road surface. My car still has some impact harshness, but that’s attributable to the 225/40-18 Conti ExtremeContact Sport tires. Some lightweight 17” wheels and 225/45-17 tires are in my future; as planned.

Looks good! Can you get some other pics on level ground? How much have you driven on them so far?

With my past experience with coilovers on a daily driver I just couldn't do it so I ordered up some TruHarts last night with ebay's 15% off coupon. I also ordered up the coupe isolators and spring shim kit from Chris at Redshift. Hopefully these help some of the issues I'm having with the H&R springs.

Nice buy! I just got the RedShift shim kit installed this morning and it worked wonders for the issues I had with Eibach Sportlines + TruHart Shocks.

The difference in height between the front and rear went from a 0.6in. difference to a 0.2in. (Which is what it’s supposed to be) and leveled out the car perfectly. It also eliminated any rubbing I had on the front fender liners when doing full-lock and high speed turns. I’ll post better pics after I get my front camber adjusted and the car cleaned up. It’s been raining hard out here so she’s a bit dirty. Here’s a comparison between how it sat before the shim kit (bottom) and after.

Looks great!

Looks great!

Thanks!
I finally got the chance to clean up the car. The difference is hard to see but very noticeable when driving. Before the Redshift shim kit, I was rubbing my fender liners on bumps and full lock turns. After the shim kit that no longer happens. It gave me just enough lift to provide clearance. Went from tucking the top of the tire to hovering right above it. The sun makes it hard to see sort of but the up close pics really show the 3/8ths increase in height.

It sits and rides exactly how I want it to now. The top halves of the pictures are before and bottom halves are after.

Looks great, I already have the Eibach springs I'll be doing the same thing when I hit 70K miles. Question-what size rims and tires are you running?

70k miles is exactly when I ended up replacing my HFP struts w/ Truhart. I have an HFP coupe so I’m running the factory 9th gen Honda HFP wheels. They’re 18x7 I believe and wrapped with Pirelli P-Zero 225-40-18.

Just saw the request for better pictures of my setup, hope these help some. I’ve only put a few hundred miles on them in the week they’ve been on the car. They haven’t settled any more since day two. The HFPs were used springs, so figuring that’s why they settled very quickly. I’m on 18x8 +40, with 225/40-18 tires.

That does look much better. I can see how that would make the difference. I am debating on whether or not I even want to install my fronts lol.

I’m no expert by any means but I think the best bet would be to have matching struts all the way around. Just get the $35 shim kit from Redshift and everything will be fine.

Anyone know if the shim kit can be retrofitted to the front without taking apart the strut assembly? I have truharts mounted in front with eibach prokit springs, and its a bit too low, scrubs the inner liner sometimes. Thanks.

No you will need to compress the spring and remove the top mount to install the shim.
I guess you could try placing it between the top mount and strut tower but I'm not sure if it would even fit that way

Okay...yes...HOLY Thread Revival...

Now; a couple questions:

1) How are y'alls Truhart struts and shocks holding up so far after all this time? I just ordered a set from Chris at Redshift, for my 2014 Si sedan, and am curious about durability.

2) Chris told me that although the strut housing is 3/4" shorter than stock, the spring perch itself is only about 1/8-1/4" lower than the OE strut's. Most of you have commented on the extra drop in front, with the Truharts. What I'd love to learn is HOW MUCH extra they drop? 1/8"? 1/4"? More?

On a side note, something that may solve a strut installation problem I saw mentioned:

For you guys with sedans, that are mounting Truharts in the front, you need to replace the lower spring isolators with COUPE isolators.

The Truhart struts are designed for Coupe/HFP-style springs, where the left and right are wound in the same direction. OEM sedan front springs are wound in opposite directions left to right. This is why you're having fitment issues, when putting the old isolator into the Truhart strut. You shouldn't need to trim or cut anything.

Again...I'd greatly appreciate updates on how you like the Truharts so far; and also, how much lower you feel the front struts drop, compared to the OEM struts (springs remaining the same before and after).

Going for the revival thing once more LOL. Not worth starting a whole new thread, but thanks for shedding some light on the spring fitment debacle. Plus wanted to hit you guys up and see if you have any long term thoughts about these struts. I have a sedan so I don't want any noises and don't want to install everything and have to rip it back apart so I want to get the whole spring isolator thing figured out. You or anyone else have the part #s needed? In the aftermarket department (monroe, kyb, etc) all I'm seeing is a right and left part # for those isolators on the bottom front that slide over the springs. Need to know if I need two lefts or two rights if anybody knows. Already have KYB strut mounts (mine are worn and making clunking noises) and ordered Tanabe GF210s (seem like the best option for a slight 1" drop but with higher spring rates than factory). Think they stopped making those springs as they're getting hard to find.

Edit: Think the parts site that I was checking out (partsgeek) didn't have it listed correctly but on rockauto they're showing one part for front lower insulator for the coupe: KYB SM5707
And the sedan ones seem to be KYB SM5705 & SM5706. Judging by the pictures the sedan ones have a slightly different design and are missing the little peg which I assume is there to help hold the spring in place a little better. Still interested in hearing about how these hold up after a couple of years. Strange that this forum seems fairly inactive. Still see tons and tons of 8th and 9th generation Civics on the road.

Sorry if I'm reviving a dead thread, but i've had these for well over a year now and can report that they are still going strong, my Si is on DD Duty so it goes over the same bumps and holes day in and out with out so much as a peep!

I've also heard from Chris over at redshift for any drop over 2.0 inches that this is a better option over the Konis ( I Run the Sunk 2 Drop Springs witha 2.25 Front and 2.0 Drop in the rear) i have no illusions that the Koni is the superrior shock, but the Truhart's are a solid contender and are better suited to my situtation

I would def recomend to anyone looking for a drop in shock option, def stand behind the Truhart Shocks for the9th Gens!

Just a few more recent images of my Si, about a year after the shock and spring combo went in

Did you have to roll fenders?

 

[Joeyg401]

Anyone still on here? Just got the Eibach pro kit, triggers struts and I went to Honda and ordered every other OEM component to the shocks so I don’t have to take apart the stock ones…..opened the Eibach box and it’s saying they’re for a 12-13 si when I swear I ordered for my 2015 sedan base model….
