Just had a set of kumo ecsta v70 medium compound track day tyres put on my 2wd Sapphire and I am very impressed with them. The car has koni adjustable front struts with eibach lowering springs, rear bilstein adjustable struts with eibach lowering springs,front and rear custom made adjustable strut braces and poly bushes on everything.Being a 2wd with a lot of power wheel spin and power slides have both been reduced and acceleration improved since fitting them. For track days and fast road use they seem ideal. Is anyone else using them?

 

Mike rainbird uses them on his track escort cossie and they seemed good when he took kept in them

On our puma race car we are trying federal fz201 and they seem good!

 

Yes, I use them, very good
