We have the H&Rs available

If you have any questions, do not hesitate to ask them!

 

Who owns this blog?
Too lazy to check and don't care much but it seems some of the info are lifted straight off of my writing and my posts on this forum - words for words. For example that discussion on progressive vs. linear spring. I am merely an amateur, they shouldn't really quote me as "information."
BTW, all lowering springs are progressive. This in itself is not necessarily good or bad; I believe some OEM springs of either GT3 or GT2 are, or at least, were, progressive as well.

Also, this is first time that I hear that Techart is made by Eibach. Considering the blog lifts information off my writing, is this accuracy confirmed? Not that it matters, just curious.

For OP, GMG would be my first choice, but if GMG is no longer available, I would consider Techart, mainly because I suspect it is stiffer than H&R, and I like stiffness LOL. Before Bilstein released the Damptronic Coilover, many on this forum had used Techart lowering springs. One of these people was "eclou," the moderator of this forum and someone I trust very much. Although eclou later switched to Bilstein, he had reported excellent result with Techart springs.
I have no knowledge of how good the Eibach springs are, but worth considering mainly because of the name/reputation, and that they make the GMG springs.

 

I will confirm this. Techart Springs are certainly made by Eibach. When we took delivery of our 2009 Turbo, it had Techart by Eibach springs.

Also, I found this photograph that helps corroborate my findings.

 

Love my GMGs, this is how the car should have been stock.

That said, I don't know I'd have waited 6 weeks to get them.

 

Eibach makes the GMG springs for them to their specs. Eibach is a good quality part.I used H&R for my S but on the turbo I went GMG.

 

BTW, for anyone who has lowering springs and yet want more stiffness/tightness/precision and less body roll, I would very highly recommend adding anti sway bar. Anti sway bar is probably the single most cost effective way of "fine tuning" your suspension, and when done right and with the right components, could change a mediocre softie into a serious sports car by reducing body roll. In my Bilstein Turbo, the GMG sway bar makes a night and day difference.

IMHO the rec. for sway bar applies particularly to owners of GMG lowering springs, as those springs are designed as a system with the GMG sway bars. Do keep in mind that if you are using the polyurethane bushings, you need lubrication about once a year as these things freeze and cause binding if not lubricated. (The stock rubber bushing causes no such binding.) The ability to re-use stock/OEM rubber bushing, if so desired, is why I would think it might be a good idea to consider after-market bars that have the same diameter as the stock bar. The GMG bars are, I don't know what else is.
