Since mistakenly fitting stock springs to the front, the handling has been ruined!

I've been toying with the idea of getting a 2nd car, but I do so few miles, I thought instead to get the 306 sorted once and for all.

It's had new Michelin Pilot Sport 3s all round:




And is now getting treated to:

Bilstein B12s inc. dampers, Eibach springs and new OEM top mounts:






Full Piper stainless steel exhaust system:




Exhaust gubbins:


New window regulators:


Pug1Off short-shifter:



Then it should be a pretty decent daily driver. Other than these mods, I might consider cams in the future, ITBs but it does start to get very expensive!

Really good update, I'm sure the suspension will hugely help. I've got B14s on my Clio and they're superb. I did look at cams and ITBs, but it seemed like a lot of money to spend for another 30hp...

Nice, B14s are adjustable aren't they? I did look into Gaz coilovers but heard they are too stiff for everyday road use. I hope these B12s are a nice compromise. I had a B12 setup on my old 9-5 Aero and they were superb, made the whole vehicle feel more reassuring in all environments.

Yeh a nice compromise might be just cams alone, which on a GTI-6 can take it from 167 to around 190 bhp. ITBs with the same cams, looking at around 210 bhp.

That's more like it!

I always liked the look of these back in the day. I feel the interior lets the pretty exterior down somewhat.

Yeh they're very basic inside, I sat in the back earlier and it's very cramped! The seats are pretty nice with leather/alcantara but the driver's seat is quite ripped up.

Pleased to see you committing to it! A great selection of mods and upgrades too. What's the exhaust like? And as you requested earlier here is a pic of mine:

Thanks, not on yet, hoping it sounds nice and raspy. What suspension is yours sitting on? It sits perfect!

So it's had the B12s, new top mounts and PS3s fitted, and it still handles like st.

Really don't know what's going on with this thing, it's so wallowy!

Ride height looks perfect now, mind.

Well, it looks good at least.

Steering issue perhaps? Or new dampers not adjusted correctly or a duff one/pair?

Good luck getting it right.

Thanks, I'm thinking rear axle, perhaps Imaxl used parts wrong for this model frown

It's just on Eibachs on the front and B4's all round, not sure if the rear has been lowered but don't think so. Mine handles nicely but I have really wooly steering, despite refreshing the front end. Would quite like to get to the bottom of that

Presumably the passive rear steering means if the ride height isn't as intended it'll track a bit strangely? Also I'm not sure if the rear linkages are especially complicated to allow the geometry, but I had the radius arm bearings fail on my ZX, with the same set up, and that really buggered up the handling, so it's worth checking all the bearings/bushes in suspension are still tight..

Are you absolutely positive the springs are correct, it looks to be sitting high in my eyes? Just looked through some photos of one I had many years back, which was standard and on factory springs/dampers.

Mine sat like this (old old photos) and handled very well, so much fun to chuck around as it cocked a rear wheel.

The springs are Eibach pros, which are 30mm lower than stock. Which springs were you using? Rear axle was lowered by 15mm, perhaps they need adjusting. I'm thinking something is up with the rear axle and Imaxl have used parts not fit for the GTI-6. The handling is very uninspiring, awful.

Yes correct. Also had new OEM top mounts and Eibach Pro springs.

Mine was on factory springs and dampers, I replaced the dampers at some point during my 8 year ownership, for some slightly stiffer ones recommend on the forum at the time. However, dampers didn't affect ride height obviously. Yours looks to sit higher than mine did, however I recall a friend changing the front springs on his and it suddenly sitting higher as well, he sold the car though so never go to the bottom of it.

I've never known a car to be so complicated to tune, my M5 was less faff! Hoping sorting the rear axle gets it driving properly again.

I seem to remember that to lower these (like the 205) you need to adjust the torsion bar? Is it possible that when fitting the new suspension, if it had already been lowered at the TB, they've possibly raised the TB too much and that's why it's sitting so high? With lowering springs it definitely should be lower than it is I'm sure.
