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

Hub centric rings have made a large improvement. No steering wheel shake until I use the brakes and even that seems less than before. Onwards and upwards...

Oops now I notice your last line about the same ride height, doesn't that mean therefor that there is again only another 1" to the bump stop ? which I believe is the reason why lowering springs need to be much higher rated.

The problem may be your 40 profile fronts.

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.

Hi RT,
I am working through problems with the car and now the focus moves to steering and suspension issues.
Recently you helped me identify the source of some wheel shake, which will be fixed when I get home tonight to hopefully find some hub centric rings delivered. Yay !
I have a series of other issues due to modifications made previously, mainly wrong wheels and suspension.
I want to check the alignment settings but for now I want to ask you about the post you made above in 2015.

I have some Koni inserts (set to softest) with some Eichbach Pro springs. I believe this lowers the car by an inch (?) which in itself does not please me, as I need help to get out of the car :o) but also I have read that lowering an SW20 can initiate issues around roll centre and therefore camber etc. I like the idea of going back up to the softer stock springs as the Eichbachs are too harsh for Sydney roads, but my q is whether the Konis will lengthen that inch ? and if so, surely their working range/travel is designed for one spring length than the other ?? seems odd.
I guess the fact that the Koni inserts are inside the stock strut probably means they will lengthen back 1" to stock spring length. Lastly is there a diff between the stock front springs of a 91 to a 92+ vintage? I guess there would be plenty of sets around with all the coilover fans.
Another of the issues I have is curious, besides the bump steer of these wide front wheel/tyre with incorrect offset, is that occasionally under braking the wheel is pulling to the left, sometimes. I am sure it is not the caliper or brakes and have check ed them, I suspect it is a worn bush or strut cushion that is altering the caster on one side, or something like that. I'm not really sure how to check those components. Any thoughts ?

cheers,
Nigel

They are discontinued. I contacted 4-5 places in US， even those that said they had /showed stock. But when I said did you know they're discontinued they said in that case they can't get them. Only place you will find some Is second hand on MR2OC but apparently it was going to cost US$175 to ship， that was last month.

I bought mine from Eibach Australia http://www.eibach.com.au/
They didn't have them in stock, took about 2 months

I gave up trying to find TRD springs and bought Eibach Pro-Kits instead.

I have seen report that they are no longer made.

Anyone know where to get these 'soft' TRD springs? I'm getting sick of going through the Japan catalogues haha

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.

Anyone know whether there is a difference between the springs delivered on a ADM shock and a JDM shock.Doesn't seem to be in terms of part numbers available from Toyota. Did ADM cars come with blue bilstein struts too, I've only seen black sealed struts on later ADM cars?
I do want to get new springs, but if I can find some front springs to match my rear JDM Bilstein springs I can try them out first. I realise they are getting on in age and would be worn, but should give me a guide on what to expect.

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.

It's worth aiming for the Soft-type TRD's, they're firm enough, imagine the hard-type would be a bit much.
As mentioned earlier - a good set of Gen3 OEM springs will ride nicely, especially if you're already running 17's with thin rubber...

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".

Did you get the harder TRD springs Reddtarga? I've got the softer progressive wound TRD springs on my car and the lowering is quite moderate (around 1-1.25") and while they sharpen up the handling of the car, the ride is very comfortable and compliant.

I've always been very happy with them.
