T-bar wheel rate

Finally starting to reassemble my swinger (3.5 years). Eaton did my leafs, I believe they made them at 135lb spring rate. The car came with MP 920 t-bars. My question is : do I want to match the t-bar rate to 135 or is it a proportionate thing, like since the front half is X amount heavier should the bars be the same amount heavier? We're talking about a spirited driver with occasional road coarse driving. Thanks
