Hi All,

I purchased the PCA-WRX-001 kit (made by Eibach) from Peter Cambridge (Ex-Prodrive Engineer) of PCA Dynamics back in 2018 for my 2007 Subaru Impreza WRX (Hawkeye). I've been really pleased with the set-up of my WRX (30mm lowered at the front and 15mm lowered at the rear according to Peter) but unfortunately, one of the rear springs has now snapped/ broken on one side.

Some of you may be aware that Peter sadly passed away a few years ago so I reached out to Eibach to see whether they would be willing to supply them. The response I got from them was that a single vehicle set would be somewhere in the region of £4k-£5k to make, where as if they were to make around 20 or so kits it would be more in the £200+ region per set.

I understand that Post COVID, the Germans were hit quite badly so when the opportunity came for Peter to try to get them from Eibach Post 2020, the quotes went up to £400+ per set so Peter was looking at an alternative UK supplier instead. I'm not sure whether he was able to do so and whether he supplied any new sets Post COVID.

I'm curious to understand whether there would be any interest in this kit from fellow members (especially given how there aren't that many of these on the road anymore)?

 

Were you able to supply the exact specs to Eibach or was it a general query?

 

Eibach are fully aware of the spec and are still able to produce them. Their response was as follows:

"Yes I was fortunate enough to have know Peter for many years before he passed, and some of his Prodrive kits have been kept in manufacture for specialist in the UK. Unfortunately, the particular kit you have is not one that has been resurrected by any of the UK specialists and none have been manufactured since 2019."

 

I've had a set of the springs for 10+ years but never came up with a perfect shock absorber combination. It would be useful to know the exact spring rates, as there are a few different rates suggested online.

 

I'm not sure either but the combination I am running is as follows:

- Group N Top Mounts
- KYB Ultra SR Shock Absorbers
- PCA Dynamics WRX Springs

 

a possible solution would be to remove the other rear spring and send it to somewhere in UK and ask them to make you a pair?

Thanks Gambit.

I've been told that Pedders are pretty good at re-engineering springs a well. However, as it's a daily driver I don't have time to be able to do that so am starting to explore alternatives options for the short-term. In most instances, the rear springs that are available on the market at the moment seem to lower the rear on the Hawkeye by more than 15mm.

 

The guru 2pot is bound to be along shortly as he knows everything about suspension.

 

I've tried KYB Excels (too soft - they burn out quickly) and Koni Inserts (too stiff). This is for a daily - YMMV for track work. I may get the Konis refurbished and re-valved softer in the future. Running Whiteline springs with KYB Excels currently.

 

I've reached out to 2pot directly and he has definitely been of great help!

 

You can get (or make) spacers that go between the rear top mount and body to adjust the height.

 

Can't of been of that much help otherwise you wouldn't be on here. Caveat emptor

 

I actually got in touch with him after I posted this!

 

The KYB Ultra SR are definitely stiffer and mine is also a daily driver!

 

Just stick a set of standard rear springs in till you get a pair made up.
