My griff is so low to the ground it will catch underneath on cats eyes when overtaking, especially with a passenger and a full tank of juice. As much as the low look is good and the handling is superb with the nitron set up, it's becoming a pain with the damage being caused. The exhaust is taking too much of a pounding and is becoming dented under the tail pipes and the flexi bit in the middle has already been welded previously, and just last week one of the anti roll bar mounts was ripped off.

Speed bumps are a no go area.

There is no room to get your hand between the rear wheel arch and the top of the tyre. Is this ride height the result of the nitrons or is there a way to raise the rear end about 25mm or so? I've tried adjusting the nitrons but it only affects the stiffness.

Help needed please!

Sounds like you need to adjust/compress the springs more, using the adjustable spring bottom ring??

adjusting the ring at the bottom only seems to stiffen the spring.

if you wind up the collar at the bottom of the spring
yes you compress the spring, but you are in effect raising the car away from the ground.

first measure the distance from the bottom of the collar to the bottom of the thread on the shock, raise it say 10mm, then do the other side, the fronts need to be the same measurement, bnut the backs will be slightly higher, but, both rears being the same height.

if still not happy, or unsure on what you are doing see someone who deals with tvr suspension and get it sorted.

You can also do it by counting the threads under the locking bottom nut,,Try 7 threads to start of front & rear if still bottoming out turn it up 3 more threads at a time,, this should cure it without loosing to much ride height,,,

You must set the ride height correctly.
The suspension doesn't work properly if set to low, you will achieve better handleing when set at the correct height.

Reset ride height.

Rear 155mm.
Front 145mm.

Measured under the outrigger triangular plate welded to the outrigger corners.
I am using standard + 20% springs which are an improvement over standard springs and still are very compliant.

Rule of thumb;

One finger inbetween wheel arch and tyre, front.
Two " " " " " " , Rear.

Best results when set accurately.

Not a grief, but you get the idea!

You really don't want it that low, your anti-roll bar won't be working properly and you'll be getting a fair bit of body roll...

I'm with HCM. He demonstrated how low mine was a couple of months ago so I raised mine by about 30mm F&R. Way better ride and fewer groundings. I now have three fingers at the rear and two at the front IYSWIM.
