im looking to update my mx5's suspension but i feel like i dont quite need the performance nor the hole in my wallet for coilovers, but every i seem to look there are divided thoughts! so yellow koni shocks and h&r springs 40mm drop or bilsteins with eibach springs 30mm drop?? im also open to other suggestions but i dont really want to fork out more that 600/700 and know that if i went for coilovers at this price i wouldnt be getting particularly brilliant ones.
