Im asking for advice. Its 159 , 1.9 jtdm ti.
Im in north london.
Cheers for the extra info, the Ti has different springs to Lusso spec etc, luckily it makes it easier as other companies offer similar spec to your oEM ones.
Alfisti are good value for the springs, or try TMC motorsport
, £99. My own Ti springs snapped within 200 miles of each other (and in the same place!), and they are a known failure (assuming it's the rears?!), so strongly suggest you replace both on the axle. For the price, you may as well do all four. The Eibach will be far better quality and will improve the ride over the OEM ones (made by Sachs), they are maybe 5mm lower, but I've personally not had any issues.
If you have the budget, try the Bilstein B4 shocks too (inspect the current ones for leaks before starting, then you can order replacements if needed).
Most garages should be able to do the job, so if you can get your dad's garage to do them at £50 a corner, then go for it. Otherwise there are a number of good independents who will be far more reasonable (knowledgeable and helpful) than many of the authorized dealers
