Installing strano & koni's ?
 
Got the old shocks out went to assemble the koni's and strano springs with the springs fully decompressed they are kind of loose between the bottom spring perch and the strut mount. Is this OK or did I miss something. I didn't move the lower spring perch down on the koni. I was also wondering am I supposed to transfer the dust boot over from the top of the stock decarbon to the koni. I don't think I have to because how would you adjust the koni shock. Do you also use the black piece of plastic from the old shocks that the spring sits on?

There is going to be a little free play between any lowering spring and a stock replacement shock. The lowering spring is shorter than stock, which is why/how the car is able to sit lower with a higher spring rate.

Thanks Major kind of what I thought but had to make sure. As far as mounting the rear shock i was wondering what size bolt to secure the rear shock to the rearend. The konis didn't come with a bolt to secure it to the rear.

It's been a very long time since I installed my 4th gen rear Koni's but if I remember correctly the bolt/stud was integrated with the lower shock busing.

These koni's have no bolt what so ever intergrated with them.

I would start with a 14mm (10.9 'grade') or 9/16" (Grade 8) bolt with fine threads, about 2.5" to 3" long. Besides the matching nut, you will want a couple nice/thick flat washers (and maybe a few extra to space the shock out away from the rearend mount a little), and a lock-washer before the nut.
If those bolts won't fit/too sloppy, then try a different diameter-- but those should be real close to the size of the rearend's shock mounting hole.

I just went around town and apparently all the hardware stores in town close at 5 what the F@#K.

be sure to post pics when done

hey, I'm doing mine monday. how do you get to the rear shock to adjust it the way it's positioned on the car, I just looked at mine and wow there's no way.

I put mine back on however I'm wondering if the plastic piece can be left out and have no adverse effect to the suspension noise? I would cut down more of your suspension travel though.

I thought it would be a good idea to put them in so I am going to rip the front back apart and install them.

Ah, our ill buddy Sam didn't send instructions or complete hardware.... how nice of him. :eyes:

You must have 3rd gen rears so they must come off. 4th gen has the knob and you access it from the top of the shock where you access the top shock nut. I had to cut a couple small slits in the carpet but you really can't tell.

...I've got Strano springs and his 4/3 Koni shocks on order... Are you saying the rears don't come with ANY hardware at all?! Or, do you think it's missing? Can you post up pics of what you're talking about on the rear shocks? I'm hoping yours is just missing the hardware...even my current Gabriel shocks came with everything I needed to install them! I can't imagine Koni wouldn't do that as well...

I will have pics up in a few hours. Car is really dirty and of coarse I have to cut the grass. The only thing that was missing was the bolt to mount the shock to rearend. Just ran to the local hardware store and picked up some bolts that fit the shock perfectly. Can't remember exactly I think either m12 3inches long or m14 3 inches long with the nuts to go with them. It also helps just to take the shock with you. I will have pics up later.

With the advice from 500hpZ06 here what I did to mount bottom of shock to rearend.

That's a PERFECT stance! Now I'm really looking forward to getting my set-up!

Did the washers come with the shocks? Or, did you have to buy those separately, along with a new nut?

bene May 17, 2009 09:26 PM

Holy schitt, that is low... I see you still have stock Y pipe and exhaust manifold. GL w/ future exhaust mods.

car looks beautiful man! i love the strano/koni set up :)

Had to buy the bolt, nut and washers.
