Ok people i installed my coil overs on my 91' 240sxabout a month ago, Right away my rear struts blew, so i jus figured they had never been changed so it be ok i jus bought new stock rear struts. Did that and by the end of the weak they had already fadded a whole lot. So then i jus went and bought KYB GR-2 struts all around. Ive had then on for about 3 and the back are giving out again, bad! Please what struts will last, poeple i talked to said that all kyb and tokico struts are of factory length, but i dont think thats true. What struts are lower chamber for lowered cars. Pricees and info appreciated!

I got Apexi World Sports and the rear struts blew out in less than 10k, I just been riding on them, but I'm in the same boat as you...

Just get the AGXs, they are made to work with lowered suspension. What coil-overs do you have?

Sounds like your springs are shot along with your struts, thats why your struts keep dying. I would check your springs asap. Goodluck

Yeah, how much is your car lowered? Cuase on my AGXs it says not to lower the car more then like 2 inches with them, I believe. Could be wrong, but I remember reading that somewhere on them.

I don't know why you want your car so low, you may have to spring for some really nice Koni's, I think they make a brand especially to work with 2+ inch lowered cars. KYB AGX's are used alot with Eibach Sportlines with great results, that's the best bang for the buck IMHO

The problem is you are running an add-on sleeve coilover to an existing strut. These kinds of coilovers are designed ONLY for looks, they are not performance-oriented and do not provide any sort of ride quality. If you want coilovers, buy REAL coilovers, otherwise stick with a good set of lowering springs and struts. Your coilovers will continue to blow any type of strut/shock you put on it, guaranteed, since they're not built to handle them. A good strut has a given range of compression, you're cutting that range in at least half, forcing it to bottom out.

Elaborate? You have a brain, right? Your OE strut/spring set is a matched pair, the compression stroke is related directly to the height of the spring. By switching to say, an Eibach Pro-Kit, you lower the car about 1.3", therefore reducing the compression stroke by 1.3" also. This is not bad, since the new springs are stiffer and don't increase strut travel greatly. Now, drop it 2" or more, with a set of 'rice' style coilovers, and you've effectively reduced travel by over 2", however the compression stroke has not decreased. What happens when the stroke, now being 2" shorter, must accomodate a large bump? It can't, since the total travel is less than what's allowed. You probably hear noises when the car hits bumps and such, what would you think that is? That's the piston reaching the lowest possible point and bottoming out.

In another example, jump on a trampoline. Your highest acheived point , say 6 feet, is equal to the total travel in the compresion stroke. Now, take that distance and reduce it by half, BUT continue to imagine jumping the same distance, 6 feet, as before just not reaching the same height since it's been reduced. You will technically have to hit the ground in order to make that happen. What does hitting the ground feel like?

Well ok people, I just ordered some tokico hp struts for the rear and I plan on ordering some tokico Hp's or Kyb adjustables for the front. Will these struts fix my problem??

Please, never use the term 'slammed' to refer to a lowered car.

1. It reminds me of that horrific dictionary that freak posted of so called 'race terms' or rice terms...something like that. Either way I lost 15 years off my life to just opening the page up.

2. it makes you seem like the kind of guy that auditions for gay p0rn flicks

3. People will also think you drive a riced out civic, and that you wear nothing but a white haynes undershirt, have bleached hair in an attempt to be someone you're not.
