Have just taken my car to the suspension specialist to hopefully solve the grip and reduce the push out of corners.

I have played with the adj front bar stiffness as well as refitting the non adjustable stock bar and have 2 deg neg and 7 deg caster on the front and app1 deg neg rears and no luck.

Car will be corner weighted,front and rear Konis shock dynoed and reset to suit stiffer springs.
Rear struts converted to coilovers Fronts done previously as there are far more springs available for the CO's
.

Rear spring weights will be increased proportionately over the fronts in the rear to reduce understeer.
Both F&R spring rates will be increased to be more track orientated as the car is mainly for motorsport but still driven on the road app 100 k per month.

If the car is too twitchy/taily/loose then can refit HD bar and try different stiffness to reduce the loose rear IF that happens.

Sounds like you are a man with a plan!

Don't forget to tell whoever is corner weighting the car your all up racing weight so this can be added to the driver's seat.

Thanks 4 the reminder Steve will tell them 85kg

im not 85kg wet lmao !!!

 

[geraint13]

sounds like you have clear goal there bud, hope it goes well !!

Hmm I have some way to go to see my racing weight!

 

[TCJBOLDIE]

No driver corner weight KG's LF 339.5 RF 358.5 LR 303.5 RR 299.5
With 75 kg driver the corner weight KG's LF 341 RF 393 LR 319 RR 324

They tell me the car will be transformed with the uprated springs and adjusted corner weights when finished
Have a Time Attack track day coming up next month so hope they are right

Have asked that they remove the spare when doing final CW adjustments.

Have to add 10 kg when setting final heights/CW's

PS I had spaced all the numbers directly above each other for ease of comparison BUT they dissappear when posted as Julius would say "why is it so"

 

[TCJBOLDIE]

Just checked on progress and struts, springs and dampers all done and still to be corner weighted again to adjust the ride heights and front to rear balance and a 4 wheel alignment with 3 deg front camber and 6 deg caster.

Just back from my usual app 100 k test drive circuit and the car seems/feels far more responsive to steering inputs as it changed direction faster and had to reduce amount of lock on a couple of corners as would have put the inside wheel off the tarmac.

Looking forward to exploring this new grip level at my Time Attack track day on Thursday the 12th Feb.

Sounding very good there Rad, looking forward to the 12th of Feb update
