I have a 92 prelude. originally i had eibach pro-kits on there with tockico blues. i always noticed that the rear was higher than the front and never really liked the overall drop, wanting it lower. never had any complaints about the ride quality tho. i later went ahead and ordered a set of sportlines for the lower drop that i wanted. again the front was lower than the rear. now, i hate the ride quality. the spring rates seem to be too soft for the amount of drop this set gives leading to constant bottoming of the shocks and/or the chassis. the only real part of the problem is the front end that bottoms too much. SOLUTION: i put the pro-kit springs on the front of the car and left the sportlines on the rear. this so far seems to have leveled out the drop difference problem front to rear while greatly improving the ride quality and handling. What do you guys think? I'll post pics wen i get a chance

anyone ever do this or hear of it?

 

Generally its a bad idea to mix springs from different kits (i.e., not linear rate race springs like you find on GC coilovers).

But in your case I think its OK because 1) the spring rates aren't that far apart. Its not like you're running 800lbs rear and 200 lbs front. 2) You're using Eibach front and rear and both springs are a Prelude application. If you want to do it, go for it.

I have to ask though, if your shocks are bottoming out, don't you think that the shocks could be a problem? Tokico Blues are kinda soft - basically the same as OEM. Also, the Sportlines are meant to drop slightly more in front than in the rear. If there's a really big difference in front vs. rear, then the shocks are sagging. the Sportlines are wound to be pretty soft on the outer coils but the inner coils are a pretty high rate (remember its a progressive wind). There's no way the bottoming out is due to the springs being too soft for the vehicle, that is if you are truly bottoming out.

 

If it feels better and you like the drop....I say rock it!

 

Well it sure feels like its bottoming out, but this would be the first time I'm experiencing bottoming. Usually a loud bang should be the sign? And yes, I know blues are quite soft. Hopefully $ will come my way for better ones. I figured this set up should help me work with what I've got rite now. I figured it would be fine doing this because they are from the same brand and from two kits meant for this car. I actually had installed the set up before I posted this and the results seemed to be very pleasing upon driving it. Definately was less nervous on slightly bumpy roads and the car just looks even now. My biggest concern was performance related. During long constant radius turns at even moderate speeds, the front suspension would bounce off the bump stops, completely upsetting the balance of the car in the turns. This I had never experienced with the Pro-kits. Never had a problem with the rear sportlines though, so I figured "I like the drop back there, ....leave 'em". Seeing as I visit the touge every once in a while (sorry had to), I dont like this unbalance. Now, the way I see it I can take turns more aggressively (because of increased suspension travel in front) while having slightly more neg. camber in the rear to better catch the lift throttle oversteer. Also I have a theory that it may help with weight transfer under braking.......maybe. Its the Ghetto Budget Hybrid Resourceful Custom Eibach set-up.
