Eiback ProKit Springs...Slammin!
If you want true performance and adjustability go for the coilovers. Save up, you won't regret it. I've been happy with my CS's since the first day I got them. And combined with the EDFC, imho there is no better combo!
I think your sc430 looks good with only a 1 inch drop. Coilovers are best if you want more drop. The Eibachs are probably the best option for us who only want 1 inch. When I was doing my research, one dealer mistakenly gave me info on the sc430, he thought that was the car I was asking about. He said he believed the stock suspension would hold up fine with only the change of the springs. Looks like you'll be fine. If you're happy, that's all that matters. I'm still trying to love the sc430 shape, it's a little easier to do with those nice wheels and drop. Good job.
After all of that rant.. I'll tell you MY opinion of MY experience.
#1 I had the Eibachs on my SC430
- Rode too harsh and completely UNACCEPTABLE
- wasn't low enough
#2 I tried the Tein Flex
- Still a bit harsh
- Height was adjustable
#3 I am now running the Tein CS
- Perfect all the way around.
Don't paint all "TEIN's" with the same brush, there is a HUGE difference between the FLEX and the CS
Pop into some of the other forums, read the experiences of others and you'll find many similar stories. Pickup the phone and have a conversation with Todd at TMEngineering, you'll get a free education.. i did and he is the one that installed my TEIN CS setup.
Sometimes saving a "grand" or more isn't worth it. Quite honestly, I hated my car when it had the Eibachs and to a lesser extend when I had the FLEX, and was considering getting rid of it.
The SC430 is a first class car and IMHO deserves only the best...
There is an excellent thread over in the GS forum that should help shed some light
Here is a Link
** Now take that money you "saved" and buy some sway bars, you *should* appreciate the improvement in handling.
Gene, I've never heard anyone say the eibach set up rode too harsh. When you had the eibach's, did you change the shocks too? I understand the combination keeps the ride nice. In fact, the set up I bought of eibach springs and tokico shocks is advertized to keep the Lexus smooth ride intact. Did you change both?
Herrage and Genearch, thanks for your insights, but I think I may have insulted Herrage or something.
Hey i guess if your happy, then thats saying alot by itself! Maybe just the spring setup is what truly fits your needs because as you said you have only put 6k miles on it in the last 2 years. Thats not a whole lot at all, so i guess my point is that for the daily driven SC's like mine (xcept in winter of course), the Tein's may be the better way to go. And eibach is quality and proven so you don't need to worry about that, but hey lets face it, coilover suspension will only offer the most in adjustability, dampening, performance and handling.
I agree with genearch, check the detailed suspension sticky in the GS forums, very useful and knowledgable tool.
