On the regular "a to b" roads, daily driving, motorways, these coilovers are fantastic. I softened the front and rear to halfway, and it drives more comfortably than stock, I shit you not. It doesn't ride like a slammed car at all.

Now once I got too my favourite roads, which would be best described as Tarmac rally stages (if you've ever driven around Banks peninsula/Port Hills near Christchurch, you'll understand) my elation turned to disappointment. Braking is improved as the car remains flatter. But in the bends, it is much disappoint.

What I should add at this point, is that I haven't had an alignment yet. I sense that my rear has too much toe in, and the front doesn't have enough toe out. Now I'll also add, and I stress this point, that I don't believe the coilovers are the issue here, I believe it's the height I have them set to. Never the less I want to share my impressions.

Initial turn in seems better and worse at the same time. I feel as if I am getting some push understeer, however I believe this will be front toe related. Beyond inital turn in, I can feel the front benefiting from the extra front camber, but what becomes immediately apparent at this point is how much body roll has increased. It is significant.

Before I put these in, I did preempt some of these issues, so already have parts on order to counter these issues. These being Whiteline tie rod ends/roll centre adjusters, front and rear sway bars and rear toe arms.

The point I want to get across is that if you get these coilovers (or indeed any others than are set to 50mm lower or more) you will need other parts if you want to still drive the car like a sports car, without having to raise it when you want to do so.

Exactly what you need, I don't know. But I think the parts I have coming are hopefully what is needed.

I'm going to start a thread now about this, as I'd like to get some convo going about creating a good suspension model at this height, or whether it's even possible.

I'll reiterate, I have no issue with these coilovers, I think they're fantastic. I think my car looks fantastic at the height too. I just don't like the fact that it handles worse now. I'm not going to track it as it is, I know I've lost a good 3 seconds a lap at a guess.

At that much of a drop you're going to need to fix the roll centers, sway bars and an alignment aren't going to cut it.

What spring rates do you have on the coilovers? The push could also be from a bad balance of front to rear rates. This you can balance with adjustable sway bars (soften front, stiffen rear).

I have front roll centre adjusters coming from whiteline, but I'm not sure what could be done to correct the rear roll centre.

I was always going to get an alignment, my buddy has an alignment shop, he just wasn't open yesterday.

My point was, until you get it done, no point reviewing the feel of the setup.

You may be able to fab up the spacer type RCA to do the job for the rear.

The title of this thread implies an oxymoron.

Even record breaking Time Attack 86s require suspension travel :)

Because I do, and I'm yet to bottom the suspension out.

I'm thinking to correct the geometry, the whiteline roll centre adjuster at the front should help. From what I can tell, to fix the rear winding the coilover out to raise the rear arm geometry 20-25mm, then using a stepped LCA to lift the hub to achieve what looks like a 55mm drop, but with the rear arms at the same geometry as if the rear was lowered 30mm.
