yeah, sooner or later you'll shake every bolt out of the car, lol.

I'd be more worried about hard springs, bad road surface and ABS detecting bounce, letting brakes off, hitting something.

really, really hard suspension just isnt suited to road driving.

Cornering fast on bumpy road could be dangerous on stiff suspension with not enough rebound. Your car bounce over bump, fly in the air, and depending which direction you turn, either you landed in the other lane in front of oncoming cars or over the edge of a cliff.

Don't laugh, i've seen myself a car bounced mid corner and landed on the wrong lane.

Stiff race suspension are designed for track use where surface is smooth, not for bumpy road.

Well just the other night, I didnt see a speed hump until it was a little too late. Hit the brakes, didn't skid, but felt that aweful bang! Was spewing for the rest of the night, cos I didn't know if I damaged anything. Can this damage the car. The only thing I noticed, was that the bumper lip was a little scratched *sigh*

But can I ask, is there anything we can do to reduce the stiffness, given that my shockies are as soft as they can go. That is, will things such as pineapples, bushes etc etc, help to reduce the harshness. The bumps and thuds I constantly hear definately do not sound good and sounds detrimental to the car. Is this normal, if so, can we reduce the effect? Thanks.

I hit a pothole just out of Gundagai with Tanabe Sustec dampers and HKS springs - snapped the sucker in half! Other side was bent like a banana.

These were already too hard for daily driving. Guess I just wanted to make sure :P

Result: New tyres needed and I put the stock suspension back in today - much more practical for daily use.

Standard bushes aid in making the car more smoother and quite. Ie. reduce NVH levels. Adding pineapples may increase NVH levels as your stiffening up the suspension, also replacing OEM bushes with aftermarket ones increase NVH.

It's a trade off just like many parts of the car.

Hippy: Not sure what's next. Will stick to the stock ones for a while. The car looks so funny - is about 2" higher! Will probably get Nismo G-Attack or Teins - I want the in-cabin adjustable controls :P

It was pretty obvious there was a problem - lots of nasty clunking noises, would hit the bump stops and bounce (springs only) over every bump. Was very unsafe.

Needed new tyres as the alignment was thrown out and the camber increased (due to lack of support) they were down to belts on the inside edge.

Not good.

Got new Sumitomos now :P

I had tannabe's install before the tein's, and they were much rougher than the teins!!

I have had the intercooler welded up twice as the bumps actually snapped the brackets!!

Also cost me a new thermo fan after hiiting a bump and punching a blade through the shroud and out the grill!!! leaving me with a nasty shudder with the air con on!!!

I took a really rough back road one day to get to steep hill climb for a bit of fun, I often wonder if that road caused this, I'm guessing it did (Sustec's as well).

yeah i have coil over Tien's. they are good. but as everyone else has stated-not for daily use. THey are good in that u can adjust the height of ur car, but they are rock solid hard. What i would like to know is for eveyrone can u keep the tien's dampers, and coilovers and just replace the springs with softer ones? ie: have everything Tien excpet the springs? Would this make ur ride softer or will it still be hard due to the dielectric materials inside the Tien damper?

i have HKS coilovers on my car.

i reckon that on the softest setting they are perfectly fine for normal driving. Of course it aint going to be no fricking lexus cos thats not the reason u bought em - u can feel the bumps and potholes, but they won't make u go 'Ouch!! my poor car!!'

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
