Sourcing TRD lowering springs 48130-SW220 (PTR04-17900-10)

"Feel every little bump"
The problem may be your 40 profile fronts. 
At one stage I ran TRD/Koni's with 50 profile tyres (15 inch wheels) and I still thought the ride was a bit firm for suburban roads. They looked good but the problem is you only have about one inch bump travel on the front.
 
If you are looking for better ride, rather than Eibach Pro-kits look for some stock 92+ springs.
I have tried both with Koni's and the stock 92+ rode noticeably softer. 
BTW, they each have about the same ride height.

I thought that the Eibach Pro's were very similar to the TRD Springs in height and stiffness?

That's not my experience.
I have tried both on my car and the TRD's were much lower lower than the Pro-Kits.
 
IMO, TRD's are a great option if you mainly want to lower your car for looks, but don't mind a harder ride.
 
 
 
 
 

Thanks ReddTarga,
 
I've read all your posts on suspension with interest as you've had them all. I know the profile of my tyres make a difference, and was hoping someone would chime in to confirm. I know alot of people run 17inch but you don't hear them complain about the ride, so I was also thinking maybe the Federals aren't as good as others. I can't complain about motorways and handling with the tyres though.
I do have some Gen3 bilstein springs off a rear cut, but no fronts, otherwise I would have them on right now even if just to try.
I was leaning to the TRD (softer type which is the part number I quoted) as most say they aren't that harsh a ride compared to stock (when combined with Koni). I did find one mr2oc thread (can't find atm) which listed the order as TRD, Eibachpro, 93+ in terms of ride quality and sums up what I've read over the years. Some of this was on mr2oc forum, so perhaps the roads there are more forgiving.
 
I didn't think the ride height was that different between the TRD and Eibach pro, but apparently there is also an older version and newer version of the TRD which differ in height. I don't want more than 1".
 

I believe my TRD springs were actually the same as the OP listed which would be the softer type.
I think the hard ones were only available on special order anyway.
 
"the order as TRD, Eibachpro, 93+ in terms of ride quality"  Correct, hardest >>> softest
Lower springs have to be made harder to stop the suspension crashing into the bumpstops on large bumps.
The stock bump travel on the front of a 92+ SW20 is only about two inches. My TRD's rode one inch lower, so there was only one inch left.
 
Of course ride is a very subjective thing, and what one person may tolerate another won't. 
Also don't forget that wheel weight, diameter, tyre profile/pressure, ARB stiffness etc are all variables that affect ride quite apart from what springs you have.
 
 
 
 
 
 
 
 
 
 
 

If ordering from US just be aware that the AW to SW changeover happened later than everywhere else. So if you ordered part X from a 1990 Mr2, you'd be getting AW parts.
 
Learnt that one the hard way.

I have seen report that they are no longer made.

Yep its looking like I'm going down that path :p cheers
