Advice Needed On Rear Suspension For Rally Car

[Twingo 1??]

I am looking for advice on a rear coil overs set up for the rear of the rally car I am in the process of finishing . After something to be used on bumpy tarmac and that won't cost the earth. Not a fan of gaz and have used avo and bilstein on other cars. I need 172/182 fitment but its not for a Clio .

Thanks

I did Mull 2016 in a Clio. I used Spax . The rears were ok but the spring rates were far too hard. The car was jumping around like a kangaroo. I am about to buy progressive springs in an attempt to allow some more bump absorption and get some feel in the back end. I will keep the spring I have for Single venue, smooth events. I am thinking of a progression between 300-500lbs

I had avo on my puma so thinking of going to them when funds are healthier!

I'm thinking of buying a 172/182 (ideally a 172 Cup) for targa rally's. So I'll be searching for forum for tips!
