Eibach Springs, not what people think?

[davo172]

So same ride quality on both sportlines lower bout 30mm prolines dont lower at all or if so how much do people reckon ??

I cant decide which to go for either ! ? Are bothe fine on std shocks or better to stick with proline on std shocks ???

Its bugging me today. Call them Pro-Kit springs. Then retailers will know what people are talking about.
I have Pro-kit springs and they are very nice. Difference is minimal over standard rideheight 10-15mm lowering max.
Sportlines will lower a max of 20-25mm if all goes well on the RS.
Sportlines are a progressive rate spring. Pro-kit are mostly constant spring rates. Both in reality offer a similar ride so the saying of 'pros for go, sportline for show' should be laid to rest. I'll dig the spring rates for these out to confirm and will post details.

Thanks Kev

Ok to run either on std shocks or not really a good idea ?

I bought new RS shocks with Pro's and that was brilliant for road driving.

True new OE shocks, sportlines and AST top mounts has made a big difference to mine for not much outlay, I have tried both on the cup and I couldnt tell much difference between except the sportlines give a cup a better stance

standard shocks are absolutely fine with them both.

Eibach were supposed to be sending them. Am chasing them now...

Spring rates of the Eibach Pro-kit
Front 18-27 N/mm; 160- 239 lb/in progressive
Rear 28-70 N/mm; 248- 620 lb/in progressive

Spring rates of the Eibach Sportline
Front 18-27 N/mm; 160- 239 lb/in progressive
Rear 40-85 N/mm; 354- 752 lb/in progressive

Fronts are exactly the same springs in both kits then?

 

[davo172]

What are the figures for lowering for a 172 ph2 for each kit. I take it the figures they quote are not for a 172.

no. but they are the same spring rate, different heights.

roughly 15mm for the pro-kit , 25mm for the Sportline

Gottcha!

Wow ! that is a surprise as the rears are harder then the AST race springs although the fronts are similar to the AST road springs when they are fully loaded.

Thanks Kam

The AST coilover for the Clio will be harder though as its not a progressive spring
