Tamora Ride Heights/Protech Settings

[Pursyluv]

Had the Protechs dampers/springs on for 3 months and could do with a bit of advice.

There are 13 clicks on Protechs, now i don't track the car, but have found myself gradually setting the ride firmer week by week to the point where i only have 2 clicks available, even at this the ride still feels quite compliant, however driving through dips the car still hits the stops?????

With what is still a complaint ride could it be the ride heights.....could a fellow owner post their ride height measurements - top of wheel arch to the ground whilst parked on a level surface.

I realise spring rates could be the issue, but i'd like to rule out the ride height first.

Thanks
Bob

so you're on 11 out of 13. have you tried 13 out of 13? they're there to be used if you want to, don't be scared

13 out of 13 is a bit of a nonsense for road use. Wrong srings or dampers not valved correctly - take them back.

[Hollowpockets]

Some of the noble guys were given wrong instructions for the damper adjustment on the protechs and were turning them towards soft instead of hard and somehow got them the wrong way round. Red is rebound, black is compression.... Just in case.

Sounds like a few have had problems with protechs. Poor show

[Pursyluv]

Unless there is a specific problem with the shocks and/or springs it does make me wonder why there are so many damper settings available when most will quite clearly be too soft!

true, but it would tell us if going a bit stiffer helps, in which case I could let him have the next bit of info to help.

If they'd been on your S, at 11 out of 13 and compliant, how close would they have been to coming off the car... Correctly valved, any where around 5-8 should be fine and compliant for the road?

[spitfire4v8]

They wouldn't be coming off the car and going back, I'd be adjusting the central spindle on the adjuster to move the damping range up in stiffness.

So not a valving issue?

[Pursyluv]

Joolz i'll have a crack at it this weekend, if still no good, do you know anyone that can sort it for me????

Could be. Or spring issue. Or bump stop issue. Or ride height issue. Really need more info.

Would it not be easier to go back to the supplier?

[spitfire4v8]

Yes. Or buy from someone whos done it before.

Ask the supplier what the fitted spring rates are (likely to be different front and rear) and then you can work from there. Cranking up the damping could increase the incidence of bottoming if the rebound damping is slowing the rate of return of the shock /spring too much, eg the suspension could "jack down". Note I've no idea what is adjustable on the shocks mentioned and the adjuster may be doing the best part of bugger all and be there for a "fashion feature" .

I bought them direct from Protech

Are you suggesting that this product is not actually fit for purpose, as it requires modification before fitting.

Before it goes any further i'm not bemoaning the product just wanting a little assistance in tweaking them - this may change if i can't get them right, but for now they feel good, apart from 3 times in 3 months the car has hit the stops.

I'll post my ride heights later.

[Pursyluv]

Ride heights are:-

NSF 640mm (615mm)
OSF 645mm (625mm)
NSR 675mm (690mm)
OSR 670mm (680mm)

In brackets were the ride heights prior to fitting the Protechs.

As i said previously it would be good to have something to compare with

Maybe you need rethink how you measure your ride heights.

To measure (as I guess you have) to the wheel arches on a TVR is not reliable enough.

Take some measurements at the front corners of the outriggers and go from there...

It's a fair point, i'll check tomorrow - i just hope someone will respond

Would the ride heights be the same for a T350

[fredd1e]

Ride hieghts alone will not determine how easy or hard it will be for the car to reach the bumpstops. the most important factor in that is the spring rates then the ride hieght /preload applied to the spring. The last factor is damping as that controls the speed the shock moves in bump and rebound not so much how far it moves.
