225 Need some ASAP fitting of new front springs in Kidderminster or Worcester

Standard 225 - 2007 (07)

Just had the "money-sapper" fail its MOT with both front springs snapped...

Renault want £106+VAT per spring and then lord knows how much labour...

I've spent hours reading here and elsewhere and there seem to be three main contenders for non-OE springs:

1. Eibach Pro-Kit
2. Cooksport
3. H&R

I see these are all lowering springs but, although I'd ideally like a like-for-like replacement, if I'm going to get better handling then I might as well pass the MOT and benefit from better handling all in one go?

I've read, however, that lowering will have long-term impact on other components... shocks, CV etc.? I've not got endless pockets and would like to stay stock so if fitting just the springs will do then please let me know...

Now, down to my main questions:

1. Would the Eibachs be a worthwhile investment?

2. Or; I've seen on Demon-Tweeks some H&R just font springs... are these the same height as OE and would anyone recommend them?

3. Is there anyone in/around Kidderminster who, for a few quid and beer, can fit/help fit ASAP? I've almost zero tools for the job...

Thaaaaank youuu!
